抄録

The authors studied systematically the recrystallization behaviour of pure chromium of 99.9% purity produced by the electrolysis of chromic acid and obtained the following results: (1) The primary recrystallization behaviour of high-purity chromium was observed to follow the wellknown general rules of recrystallization. (2) The minimum amount of working necessary for producing primary recrystallization was about 10% of reduction by rolling. (3) The activation energies for recrystallization were measured as 100 to 112 kcal/mol by isothermal measurements for specimens which were subjected to 73% reduction. (4) Grain growth due to boundary migration was observed during annealing above 1000°C for specimens which were subjected to 6∼9% reduction.
