Document Type and Number:
WIPO Patent Application WO/2017/199819
Kind Code:
A1
Abstract:
Produced is an iron-based sintered alloy in which hard particles derived from a titanium carbide powder are dispersed in the form of islands in a matrix comprising a two phase structure of austenite + martensite. The iron-based sintered alloy is obtained by mixing the titanium carbide powder, a Cr powder, a Mo powder, a Co powder and a powder of Al, Ti or Nb so as to obtain a mixed powder that contains, in terms of mass%, 20-35% of titanium carbide, 3.0-12.0% of Cr, 3.0-8.0% of Mo, 8.0-23% of Ni, 0.6-4.5% of Co and 0.6-1.0% of Al, Ti or Nb, and then subjecting the mixed powder to cold isostatic compression molding, vacuum sintering and solution treatment.
