Abstract
Utilizing relatively coarse copper powders and several sizes of silica and alumina powders, alloys containing up to 10 volume pct of oxide were made. The alloys were prepared by mechanical mixing of powders, followed by cold hydrostatic pressing, sintering, and hot extrusion. Measurements were made of room temperature tensile properties, recrystallization temperature, creep rupture properties from 250° to 450°C, and resistivity. In addition, metallographic studies were made of the resultant structures. Of particular interest was the stability of the structure with respect to temperature, time, and stress.
