To clarify the mechanisms of high temperature deformation of dispersion hardened Cu base alloys, the high temperature deformation behavior of Cu-0. 5 and 1. 0 vol%SiO//2 alloy single crystals was investigated. Tensile tests were performed in the temperature range from 873 to 973 K at initial strain rates between 10** minus **5 and 10** minus **3s** minus **1. The stress exponent, apparent activation energy for high temperature deformation and internal stress were measured. Rotation of the specimen axis was examined by the X-ray Laue method. The results are discussed on the basis of the creep theory of Ansell and Weertman. The stress exponent does not agree with that expected from theory.
