Composite dispersion strengthened composite metal powders
This patent describes a composite metal powder wherein essentially each powder particle is comprised of one or more metals and one or more refractory compounds. The powder particles are characterized as (a) having a cohesive internal structure in which the one or more metals and refractory compounds are intimately united to provide an interdispersion of comminuted fragments of the metals and refractory, (b) having the refractory substantially homogeneously dispersed throughout the metal matrix, and (c) being substantially free of oxide scale; wherein the composite metal powder particles have a mean size less than about 50 microns and a mean grain size within the powder particles of less than about 0.6 microns.
