β¦ Synopsis
The effect of thermomechanical treatment such as high temperature swaging on the creep failure mechanism of the MO-S%W alloy was investigated.
It was found that heavily swaged specimens fail after a relatively large amount of creep deformation, while slightly swaged specimens fail after a few percent of strain. In this paper the above-mentioned behaviour is explained on the basis of a semiquantitative model.
