High chromium cast iron is the third generation of white cast iron developed from ordinary white cast iron and hard nickel cast iron .The chromium content of high chromium white cast iron is more than 11%, and the ratio of chromium to carbon is between 4~8.Under these conditions, M7C3 type carbides with high hardness almost completely replace

The effect of quenching temperature on the microstructure and properties (hardness and impact properties) of high chromium cast iron was studied. On this basis, the effects of natural aging on the microstructure of high chromium cast iron and the effects of structural changes caused by natural aging on the macro hardness and micro hardness of high chromium cast iron were further studied.

In this work, a canning compression process was developed to perform hot compression deformation of high chromium cast iron (HCCI) on a Gleeble 3800 thermomechanical simulator at temperature of 950-1150 °C and strain rate of 0.01 s -1. The hot deformation behavior and microstructure evolution of HCCI were investigated.

High-chromium white cast irons are ferrous alloys with Cr contents between 12 and 30% and 1.8–3.6% C. The as-cast microstructure is typically composed by a M7C3 

The wear resistant chromium cast irons are known as materials with the extreme high abrasion resistance but also as difficult-to-cut ones. The abrasion resistance and mechanical properties of high chromium cast irons depend on a type, shape, and amount of carbides occurring in the microstructure, on matrix properties where they are lying, and on strength of a matrix - carbide junction.
