The effect of yttrium on the distributions of elements in different phase structures and properties of chromium white cast iron

Abstract

© 2020 Trans Tech Publications Ltd, Switzerland. The research results on the effect of small additions of yttrium 0-0.3 wt.% on the structure, hardness, microhardness and distribution of elements in various structural components of chromium white cast iron are presented. It has been established that small additions of yttrium contribute to the grain refinement of the carbide phase and the formation of trigonal chromium carbide (Fe,Cr)7C3 in the structure of chromium white cast iron.
