Features of the carbide steel structure, hardening by chromium carbides that synthesized during hot pressing

Abstract

The chromium carbide steel has been obtained by carbides synthesis on hotpressing. The investigation of its structure was made by the methods of X-ray and spectrum microanalysis, light and electron transmition microscopy, microhardness measurements of the structural components. The presence of two types of carbides was shown: larger with oval shape - Cr₃C₂ and eutectic thin plate carbides (Cr, Fe)₇C₃. The carbide phase is dispersed enough, especially in the eutectic structure, and it provides the carbide steel of this way obtaining to be high wear resistant. Full text download
