摘要：
The role of grain boundary slip in superplastic deformation (SPD) is recognized. Still under debate is the question of which mechanisms apart from grain boundary slip operate during SPD - some authors emphasize the effect of intragranular dislocation slip and others diffusional creep. The article considers the basic arguments in favor of one mechanism or the other.
