摘要：
Compression creep tests along a 〈110〉 stress axis have been performed on single crystals of Ni-base superalloy CMSX-2. The analysis of the experiments show that, on the one hand, the compression creep rates are lower with this stress axis than with 〈110〉, at 1023 and 1123 K; on the other hand, {111} glide is overriding at these temperatures. However, dislocation pile-ups were detected on {100} planes. This suggests that cube slip has an influence on the compression creep behaviour. © 1990.
