ABSTRACT:
A powder metallurgy produced high speed tool steel article comprising a mixture of prealloyed high speed tool steel particles coated with a hard, wear resistant material, such as a carbide or nitride, mixed with prealloyed high speed tool steel uncoated particles; the particles are compacted to essentially full density and the hard, wear resistant material is at the boundaries of the coated particles and contained in a continuous matrix of the high speed tool steel. The article is produced by hot compacting a particle charge to essentially full density of a mixture of the coated and uncoated particles.
