Engineering Subjects; Material Science and Engineering: AMIE Exam Lectures- Materials Science & Engineering | Heat Treatment | Tempering & its Type | 10.6 Introduction Previous Video - : Different types of heat treatment processes Present Video - : Tempering Tempering - : It is required just after the hardening process and is heated below lower critical temperature followed by air cooling or furnace cooling. Changes takes place during tempering - : - Carbon rejected by BCT martensite. - Spheroidization - Formation of ferrite and carbide mixture. Austempering Process - : Austempering is converted to martensite Advantages - - Low internal stess - Less distrotion - Improves mechanical property. Sub - Zero Treatment - Used to reduce retained austensile. Results in - : - Increased hardness - Increased wea resistance - Increase in internal stress , tempering required.
