What are the differences in metallographic structure between DBY450-8-I reducer after carburizing quenching and nitriding treatment
There are various differences in the metallographic structure of DBY450-8-I reducer after carburizing quenching and nitriding treatment, as follows: Differences in phase composition: Carburizing and quenching: The surface structure is mainly composed of high hardness martensite, residual austenite, and a small amount of carbides. The core is usually composed of low-carbon martensite with goo
