High speed steel sintering powder made from reclaimed grinding sludge and objects sintered therefrom

A method of producing a sintering powder made from high speed steel and alumina. This sintering powder is sinterable over a broader range of temperatures than conventional high speed steel sintering powders and at lower temperatures, thereby making sintered objects which are crack resistant and also...

Zusammenfassung:	A method of producing a sintering powder made from high speed steel and alumina. This sintering powder is sinterable over a broader range of temperatures than conventional high speed steel sintering powders and at lower temperatures, thereby making sintered objects which are crack resistant and also highly wear resistant. Additionally, the sintering powder flows readily when poured into a mold for production of a green object for sintering.
