The microstructure of the high boron white cast iron comprises a dendritic matrix and interdendritic eutectic boride M 2 B in as-cast condition, where M represents Cr, Fe, or Mn. The boride morphology is much like that of carbide in high chromium white cast iron, but its microhardness is higher than carbide.

2013. 5. 1. · The microstructure and properties of 17 wt.% Cr–2.9 wt.% C cast irons with up to 3.17 wt.% Nb additions, in both as-cast and heat treated state, have been studied.Also the

Microstructure analysis showed the presence of small amounts of Keywords: As-cast white cast iron, Manganese, Austenite phase, EDS, Carbides, Austenite.

2017. 8. 23. · CARPENTER, et al[10–11], studied 26.6% chromium white iron microstructure with XRD and electron microscope. It was shown that primary and eutectic austenite revealed a slight difference in lattice parameter and secondary carbides precipitated in the microstructural matrix of the white iron were of the form (Fe,Cr)23C6 and had a cubic

The M7C3 carbides in high Cr white iron are the primary phases of hexagonal shape and can work as the "stoppers" to decrease the wear rate during the wear application [6]. Jingjing Qing, Mingzhi Xu. 2019. "Designing a Graphitic White Iron: Microstructures and Properties." AISTech Conference Proceedings Cleveland, PA. doi: 10.33313

There are also differences in composition—cast iron contains 2–4% carbon and other alloys, and 1–3% of silicon, which improves the casting performance of the 

The general structure formed was a dendritic primary austenite in a matrix of M7C3 carbide eutectic. A very fine microstructure was achieved for 

2018. 3. 21. · White iron does not have the easy castability of other irons because its solidification temperature is generally higher, and it solidifies with C in its combined form as iron carbide.

Grey cast iron is characterized by its graphitic microstructure, which causes fractures of the material to have a grey appearance. It is the most commonly used cast iron and the most widely used cast material based on weight. Most cast irons have a chemical composition of 2.5-4.0% carbon, 1-3% silicon, and the remainder is iron.

The cast chromium white iron examined in this work contained 2.35% C, 0.61% Si, 0.62% Mn, 18.23% Cr, 0.58% Mo, 0.35% Ni, 0.46% Cu, and 0.028% P, Fe-balanced. The material was prepared by induction of appropriate raw material. Casting was then conducted from 1440 to 1460 °C into bentonite sand molds.
