AMIE Exam Lectures- Material Science & Engineering | Diffusion in Solids| its Different States | 5.2

Engineering Subjects: Introduction to Material Science and Engineering: Material Science and Engineering | Diffusion in Solids| Steady State & Non-Steady State Diffusion | 5.2 Review: In the previous video, we started with the topic Diffusion in Solids and had seen: • What diffusion is? • How diffusion takes place even in solid • Different types of Diffusion • Different Diffusion Mechanism • The fundamentals of Diffusion In this lecture, we shall discuss further about diffusion and see what steady state and non-steady state diffusions are: We shall see: • What they are? • When each type occurs? • What are the concerning factors affecting the steady state and non-steady state diffusions? Steady State Diffusion:- • Diffusion is a time dependent process • Rate of diffusion is an important practical parameter • In different heat treatment the important phenomenon taking place is diffusion and we must know how much time a particular material needs to be heat treated for diffusion to occur. • Diffusion Flux denoted by J, is used to define the rate of diffusion • Diffusion Flux states that the amount of matter which is transported per unit are, per unit time. • It is a very important criterion • It is the practical parameter based upon which many decisions for heat treatment process is taken • If the Diffusion Flux remains constant with time, it is said to be steady state diffusion. • Diffusion occurs (driving force) due to Concentration Gradient What is Concentration Gradient? • Concentration Gradient is the rate of change of concentration per unit change of position. • Higher the Concentration Gradient, faster will be the diffusion as there will be more driving force and more change will be taking place. • Diffusion Flux (J) can also be expressed in terms of gradient. This is called Fick’s First Law. • Fick’s First Law states that the Diffusional Flux (J) is equal to the negative Concentration Gradient times Diffusion Coefficient (D). • Negative sign is because diffusion is taking place from a higher concentration to a lower concentration. • Diffusion coefficient depends on several factors including What is the specimen that is diffusing? What is the temperature at which the diffusion is taking place and so on • For higher temperature D will be large and for lower temperature D will be small • If the material is small D will be large and so on. • Fick’s First Law is possible in the steady state diffusion because Concentration Gradient does not depend on time. Non-Steady State Diffusion:- • When Concentration Gradient is a function of time or when it depends on time then it is called the Non-Steady State Diffusion. • For most practical application the Concentration Gradient keep changing with time. • Diffusion Flux therefore, itself is a function of time. Here Fick’s Second Law holds. • It relates the change of concentration with time to the change of concentration with position. • These are the real scenarios that happen during different processes carburising, nitrocarburising, carbonitriding, etc. • An example of semi-infinite solid with graph is shown. With these fundamental of diffusion that steady state diffusion means that the Concentration Gradient remains constant and Non-Steady state diffusion means that the Concentration Gradient changing, you have the idea of diffusion which will be handy to understand the different heat treatment further down the line. In the next lecture, we shall see some of the dominant factor that effect the rate of diffusion A video by Edupedia World (www.edupediaworld.com), free online education Click here for more videos on this topic: https://www.youtube.com/playlist?list=PLJumA3phskPFPkGEkQe6YWZs8Z1-9xkkg All Rights Reserved.

AMIE Exam Lectures- Material Science and Engineering | Diffusion in Solids| Types |  Mechanism| 5.1
 
14:52
Engineering Subjects: Introduction to Material Science and Engineering: Material Science and Engineering| Diffusion in Solids| Types of Diffusion| Diffusion Mechanism| 5.1 Review: In the previous set of videos, we had seen the different kinds of imperfections that can be present in a solid material. In the next 3 lectures, we shall be discussing about diffusion: • What is diffusion? • What is the basic phenomenon behind it? • What are the different types of diffusion processes? What is Diffusion:- - We have already studied diffusion in our junior classes but they are specific to gases. - Similar to that phenomenon, diffusion can take place even in solids. Let us understand the basic phenomenon of diffusion:- 00:01:00 - It is the process of mass transport by movement of atoms and molecules from a region of high chemical potential to a region of low chemical potential. - High chemical potential most of the time corresponds to High concentration - Low chemical potential most of the time corresponds to Low concentration - There are two types of diffusion: • Interdiffusion or impurity Diffusion • Self-Diffusion Interdiffusion or impurity Diffusion:- If a material of iron has some carbon molecules present and the carbon molecules diffuse and move to a different place then this is called Interdiffusion or Impurity Diffusion, because small amount of carbon in the bulk Iron is considered to be an impurity. Self-Diffusion:- If some iron molecules from the bulk iron material diffuse and shift to a new location then this is called Self Diffusion. Diffusion Mechanism:- How diffusion takes place? During diffusion a step by step movement of atom takes place from one lattice site to another. The requirements or diffusion to take place are 1. There should be an adjacent vacant site 2. Sufficient energy to break bond with neighbours Where will the atom get energy to break the bonds? Atomic vibration provides the required energy to break free the bond. More the temperature more would be the vibration and more energy to break free the bond. There are two different mechanisms of diffusion • Vacancy Diffusion • Interstitial Diffusion Vacancy Diffusion:– - As the name suggests, this has got to do something with vacancy. - Interchange of atom from normal lattice site with adjacent vacancy. - Ease depends on vacancy concentration. - Direction of movement of atom and vacancy is opposite to each other. - Both "Self diffusion" as well as "interdiffusion" takes place Interstitial Diffusion:– - Interstitial are small pockets of empty spaces between atoms. When atoms are packed they have a packing fraction which would be less than 100%, so there is some space between atoms. - Small impurities can lie in between the atoms in these voids or empty space. - No vacancy required, no breaking of bonds required but the impurities or smaller atoms move through these vacancies. - Normally the atom moving is the impurity particle smaller in size. - Interstitial diffusion is faster as the atoms moving through the vacancy are smaller and the space between atoms is far more than the vacancy in vacancy diffusion. We have seen • What diffusion is? • Diffusion takes place even solid • Different types of Diffusion • Different Diffusion Mechanism • Temperature is an important criterion to tell how fast diffusion can take place In the next video, we shall see further and build on what we have seen today.

Engineering Subjects: Introduction to Material Science and Engineering: Introduction to Material Science and Engineering | Imperfection and Defects in Solid material | Two Dimensional and Three Dimensional Defects | 4.4 Review: One Dimensional Defects – Dislocation – One of the most important types of defect Two dimensional defects:- - Also known as Surface Defects – because surface are usually 2 dimensional Types of Surface Defect:- • External Surface • Grain Boundary • Twin Boundary External Surface:- - It appears at the external surface of the specimen - Surface atoms have several free bonds - High energy regions, because they have free bonds - Tries to reduce surface area to reduce surface energy Grain Boundary:- - Boundary separating two grains or crystals - Different crystallographic orientation in the grains - Grain boundary region is the region of mismatch leading to transition from 1 orientation to another - Low angle grain boundary and high angle grain boundary exist depending on angle of mismanagement Types of Grain Boundaries:- - Tilt Boundary – This is formed by edge dislocation aligning up in a line - Twist Boundary – This has angle of misorientation parallel to the boundary and formed by a series of screw dislocation  Amount of energy depends on degree of misorientation  Grain boundaries are region of higher energy and high chemical activity  Impurities tend to segregate at the boundary  Grain coarsening takes place to reduce surface area which in turn leads to reduced energy Twin Boundary:- - It’s a special type of grain boundary with mirror symmetry about it. There are two types of Twin Boundary. These are formed either by • Stress – These are called mechanical twin • Annealing treatment – These are called Annealing twin These occur in defined plane and direction depending on crystal structure Other types of two dimensional defects:- - Stacking Fault – There is a fault in the stacking sequence and one or more layers are absent in between. This type of defect is known as stacking fault. - Phase Boundary – When the two grains in grain boundary are of different phase or different material, then the boundary separating them will be called as the phase boundary. - Domain Wall – In a magnetic material the boundaries at the separation between the different domains with different magnetic orientation are called the domain walls. Three Dimensional Defects:- - These are also called as Volume Defects. - These are normally introduced while processing and fabrication Most Important Volume defects are: • Pores • Cracks • Foreign Inclusion • Other Phases In the next session, we shall see the Concept of Diffusion in a Solid Material A video by Edupedia World (www.edupediaworld.com), free online education Click here for more videos on this topic: https://www.youtube.com/playlist?list=PLJumA3phskPFPkGEkQe6YWZs8Z1-9xkkg All Rights Reserved.

AMIE Exam Lectures- Material Science and Engineering | Diffusion in Solids | Affecting Factors | 5.3
 
09:53
Engineering Subjects: Introduction to Material Science and Engineering: Material Science and Engineering | Diffusion in Solids | Factors Affecting Diffusion | 5.3 Review: In the last couple of videos, we have been discussing, about diffusion processes. So far we have discussed • What diffusion is? • How diffusion takes place even in solid • Different types of Diffusion • Different Diffusion Mechanism • The fundamentals of Diffusion • What they steady state and non-steady state diffusions In this lecture, we shall discuss further, about diffusion and see what are the factors affecting the rate of Diffusion or we can say what are the factors that determine how fast diffusion takes place. What are the factors affecting Diffusion? 00:00:30 1. Diffusion Species – The material in which the diffusion is taking place and the atom which we are talking about Mechanism – What is the mechanism, whether it is Vacancy Diffusion, Interstitial Diffusion, the size of the atom and so on 2. Temperature – How the temperature is going to be affecting 3. Alternative Diffusion Paths – In addition to the traditional paths like Vacancy and Interstitial paths there are some alternative paths which help in diffusion Diffusing Species & Diffusion Mechanism – 00:01:31 • The Diffusion Coefficient (D) depends on the diffusing species and the mechanism followed for diffusion. J depends on D for diffusion and D depends on what is the diffusing species and what mechanism is followed for diffusion. • Smaller atoms diffuse easily for obvious reasons • Interstitial Diffusion is easier than Self Diffusion • An example to highlight that different mechanism has a different rate of diffusion. Temperature – 00:04:12 • The most important factor the rate of diffusion is the temperature. • Diffusing Mechanism is not under our control. The species and the mechanism are fixed. But the temperature can be altered and it is controlled by the user. • Temperature affects the Diffusion Coefficient (D) directly and the increase is exponential. • Higher the value of T, higher would be the value of D and the diffusion will be much faster. • So the diffusion rate will be higher with high temperature. Alternative Paths of Diffusion – 00:06:46 • Regions of imperfections provide an easier path for Diffusion. • Defects such as dislocations, grain boundary and external surfaces provide a much faster path for atomic movement, as they are regions of high energy. • These provide the path for easy diffusion. • Faster than bulk diffusion. • Effective contribution is far smaller than the bulk diffusion. To Sum up – 00:08:17 • There are several factors affecting diffusion including the species in which the diffusion is going to take place and the mechanism that would follow, but we do not have much control over these. • Then we have the alternative paths such as the defects like dislocations, grain boundary and external surfaces but their contribution is far smaller than the bulk diffusion. • Then most importantly the temperature factor, which is much under our control and which has an exponential effect on the rate of diffusion. - In the last 3 lectures, we have seen and understood the process of diffusion in solid materials. - This will help in understanding the fundamental of Material Science much better with different processing mechanisms and different metal working process that takes place in metallurgy, which has a lot to do with diffusion and different heat treatments. In the next video, we shall start a new topic, where we will see the different mechanical test and examinations that we can take for a material to see its different properties.
