Abstract

In the manufacture of articles by compacting and sintering steel powder it is desired that the articles shall neither expand nor shrink during the sintering process. It has been found useful to incorporate into the steel powder an iron-phosphorus alloy powder having the approximate composition Fe3P, in a quantity to give the article a phosphorus content of 0.2 - 3 per cent by weight.
