Influence of Tempering on the Microstructure & Properties of Martensite and Bainite developed in a Low-C High-Si Steel

Martensitic and bainitic steels are two types of widely used steels with excellent mechanical behaviors in automatic industry. It’s universally acknowledged that as- quenched martensite possesses poor ductility and impact toughness, which should be tempered before putting into application. During tempering, as-quenched martensite changes from a...
