Effect of Heat Treatment on Microstructure and Mechanical Properties of High Chromium Cast Iron
Aiming to improve the size, shape and distribution of base microstructure and carbides, the heat treatment of high chromium cast iron was carried out. The results show that: after heat treatment, the stability of primary austenite in high chromium cast iron declines and subsequently transforms into martensite, the carbide morphology improves in some sort, resulting in the preferable matching of high hardness and favorable toughness.
