Powder alloys Fe-Cr-Al аnd NiAl. I. Production of powders
Lots of powders Fe-Cr-Al and NiAl by mechanical alloying of powder mixtures of the source elements, hydride and calcium recovery of metal oxides and the atomization of melts with water and gases are produced. The chemical and phase compositions of the obtained powders are studied. Their morphology and particle size distribution are studied. The recommendations for further processing of the powders for generating high-quality mold for the subsequent sintering and deformation-heat treatment of alloys are made.
