Strength and fatigue of dispersion-strengthened copper

Abstract The tensile and fatigue properties of cold-worked copper and a commercial Cu-Al2O3 dispersion-strengthened alloy were measured at temperatures between 25 and 600°C. The GLIDCOP Al-15 alloy, which contains 0.15 wt% Al in the form of Al2O3 particles, exhibited a significantly higher tensile and fatigue strength than copper under all test conditions. The mechanical properties of this alloy appear to be suitable for high-strength, high-conductivity alloy applications in fusion reactors.
