Abstract: Sinter alloys based on high-speed steel are proposed, which can be used for producing wearing parts in machinery and vehicle contruction. The sinter alloys comprise a mixture of a powder of a high-speed steel and an unalloyed or a low-alloy iron powder. While the high-speed steel powder forms liquid phases upon sintering, the mixture components can be drawn from either the group of iron alloys that do not form liquid phases or the group of iron alloys that do form liquid phases. The proposed alloys cannot be sintered to the density of the high-speed steels, nor do they quite attain the strength values of such steels, but in the cases where these limit values for strength are not critical they have the decisive advantage that they can be sintered without deformation in standard protective gas furnaces lacking extreme temperature constancy and that they furthermore exhibit only very slight shrinkage.
