抄録

This paper reports static recrystallization behavior in single crystal copper induced by micro plastic forming. Micro plastic forming tests of single crystal copper specimens were conducted by using a knife edge tool made of diamond. The formed specimens were annealed in the Ar gas atmosphere under various annealing temperatures and times. The microstructure in the micro-formed specimen and recrystallized grains in the annealed specimens were analyzed by SEM-EBSD. Through the experiments, relationship of crystal deformation by micro plastic forming and early stage of recrystallization in the single crystal copper is revealed. Furthermore, effects of annealing temperature and time on the recrystallization behavior are discussed.
