Changes in Microstructure and Abrasion Resistance during …
The satisfactory results of studies measuring the change in microstructure and abrasion resistance of high-manganese cast steel with the addition of Ti and Nb, obtained thus far in the Miller test [15,16,24], have prompted the author to conduct research on high-manganese cast steel with the addition of vanadium.

High Cr cast irons are alloys based on the Fe–Cr–C system, usually in the range from 10 to 30% Cr and from 1.8 to 4% C. Commercial alloys contain up to 1% residual Si and additions of Mn, Mo, Ni and Cu to increase hardenability. In this range of compositions most of the alloys solidify as mixtures of austenite and M 7 C 3 carbides [1].
