Heat Treatment and Surface Hardening-I

ABOUT THE COURSE

Heat treatment is a fundamental principle required for processing of metals and alloys. By controlling time-temperature sequence with/without application of stress, it can modify the structure of the materials, which would influence the properties in a desired way. This principle lies strongly on the basics of thermodynamics and kinetics of phase transformations in metals and alloys, which is the guiding factor for deciding process schedule in Industry.

INTENDED AUDIENCE

Bachelor students of Metallurgy and Mechanical engineering background and Industry people

PRE-REQUISITES

None
