Dispersion Hardening of Copper by Tungsten,

Abstract

A study was made of copper hardened by inclusions of tungsten of various degrees of dispersion in quantities of 0.5, 1.5, 3.0, 6.0, and 10.0 wt. percent. The compositions were prepared by powder metallurgy methods. The effect of the content and dispersion of the second phase on the submicrostructure, class II stresses, and density of dislocations in the base was demonstrated. The mechanical properties at temperatures up to 1,000 degrees C for copper hardened by cold rolling and sintered copper were developed. The effect of the content and dispersion of tungsten on recrystallization and softening of copper was studied. (Author)
