Metallurgical Lab Incharge Interview Questions and Answers

In hardening microstructure, one can observe changes in grain size, phase composition, and the presence of martensite.

• Changes in grain size: Hardening can lead to a finer grain structure, resulting in improved mechanical properties.

• Phase composition: Different phases may form during hardening, such as martensite, bainite, or retained austenite.

• Presence of martensite: Martensite is a hard and brittle phase that forms during rapid cooling, indicating successful hardening.
