摘要

The microstructure and texture following recrystallization in pure nickel cold rolled to 90%, 96% and 98% reduction in thickness have been characterized using electron backscattered patterns measurements. It is found that the recrystallization texture strengthens with increasing strain, but in contrast to the normally observed behaviour the recrystallized grain size is observed to increase with increasing strain. These results are discussed based on oriented nucleation and growth theories. The role of twining-orientation relationships in determination of the recrystallization texture is also analyzed.
