Study on Effect of Boron on Properties of Fe-0.77C-B Alloy

Zhenhua Li

Abstract

Porperties of Fe-0.77C-B alloy with different boron contant was investigated in order to understand the effect of boron on properties of Fe-0.77C-B alloy.The results show that the hardness of the alloy increases while its toughness decreases with the addtion of boron when the alloy solidifies in sand mould.This effect is also observed after the Fe-0.77C-B alloy is normalized under 1 000 ℃.And the properties of the Fe-0.77C-B alloy contained 2.23% boron is equivalent to the properties of KmTBCr12 alloy after it is normalized.
