Creep behavior of two Cu-2 vol% TiC alloys obtained by reaction milling and extrusion

The creep behavior of two Cu-2 vol% TiC alloys prepared by reaction milling and extrusion are presented. Creep tests were performed at 773–1123 K. The activation energy values between 109 and 156 kJ/mol and the stress-exponent values between 3.1 and 6.3 indicated that no dispersion-strengthening effect occurred.
