Abstract:

Sinterhardening is a commonly applied cost-effective process for producing higher loaded structural P/M parts. Generally, a prealloyed base powder is combined with further external alloying elements such as Ni or Cu in order to maintain the compressibility of the base powder. Astaloy® CrS is a newly developed low alloyed base powder prealloyed with 0,85% Cr and 0,15%Mo. This paper is investigating the mechanical properties after sinterhardening of various graphite and Ni additions admixed to Astaloy® CrS.
