Martensite is too brittle for engineering applications. Tempering involves reheating quenched steel to a temperature below A1cap A sub 1 Relieves internal stresses and restores toughness.
This article provides an in-depth overview of the core principles of the heat treatment of metals, aligning with the academic framework popularized by Vijendra Singh's literature. 1. Principles of Heat Treatment and Phase Transformations The loss of carbon from the surface layer
Annealing involves heating steel slightly above its critical temperature ( A3cap A sub 3 A1cap A sub 1
The FCC austenite transforms instantly into Martensite , a highly stressed, supersaturated solid solution of carbon in a Body-Centered Tetragonal (BCT) lattice. Martensite provides maximum hardness but is extremely brittle.
