... deformation does not happen to the same extent in all grains. Some grains have orientations with respect to the load that are more favorable to slip than others are. The first effect of cold work is the occurrence of heterogeneous deformation (in steel that show discontinuous yield), usually accompanied...

.... In the final analysis, it is not possible to judge the performance of alloys by considering just the γ′ phase. The existence of grains, their orientation relative to applied loads, their size, and the absence of grains (as in SCDS alloys) are all important considerations. For PC cast or wrought alloys...
