研究了不同退火温度对热等静压(HIP)纯钒组织和力学性能的影响。结果表明,纯钒的退火过程呈明显的回复、再结晶、晶粒长大3个阶段;随退火温度升高,板条状马氏体含量减少,温度高于950℃退火时板条状马氏体消失;随着退火温度的升高,纯钒的拉伸强度降低,塑性先增加后降低;塑性在950℃退火时达最大值,延伸率、断面收缩率分别为35.2%、64%。 The effect of annealing temperature on microstructure and mechanical properties of HIP pure vanadium was investigated. The results show that the annealing process of pure vanadium shows obvious recovery, recrystallization and grain growth. With the increase of annealing temperature, the content of lath martensite decreases. When the temperature is higher than the annealing temperature of 950 ℃, With the increase of annealing temperature, the tensile strength of pure vanadium decreases and the plasticity first increases and then decreases. The plasticity reaches the maximum at 950 ℃, and the elongation and reduction of area are 35.2% and 64%, respectively.
