Heat Treatment and Surface Hardening-Part II (Theory of heat treatment)

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.
