摘　　要：在较大热轧变形量的情况下,研究了工业纯钴在两种不同退火冷却方式下,不同退火温度的金相组织和硬度,同时对样品进行了XRD分析。结果发现,冷却方式对显微硬度有异常影响,确定了工业纯钴的再结晶温度,也对空冷情况下显微硬度异常变化的原因进行了分析。On the larger hot deformation condition, the microstructure and hardness of industrial pure cobalt in two different annealing cooling manners, different annealing temperatures was studied, while the sample was analyzed by XRD. The results show that the cooling mode has abnormal affect on the microhardness. The recrystallization temperature of industrial pure cobalt is determined. The abnormal changes cause of hardness is analyzed.
