摘要

The static annealing behavior of cryogenically-rolled copper over a wide temperature range (50-950 ℃) was established. At temperatures below 350 ℃ (～0.5T_m), microstructure and texture evolution were interpreted in terms of discontinuous recrystallization. Grains having orientations close to (55;30/60;0), {236}<385> (Brass-R), and {4;4; 11 }<11; 11 ;8> (Dillamore) were shown to recover rapidly and thus exhibited preferential growth during subsequent static recrystallization. At temperatures of 350 ℃ and higher, annealing behavior was dominated by abnormal grain growth. The abnormal character of this process was attributed to the relatively large spread in grain sizes produced during preceding recrystallization.
