摘　　要：针对2Cr12Ni4Mo3VNbN工业棒材退火硬度偏高问题,系统研究了不同退火工艺对2Cr12Ni4Mo3VNbN叶片钢组织和硬度的影响。结果表明:相较于两相区加热退火和不完全退火的一段式退火,完全退火具有更好的退火效果,退火后硬度最低,且炉冷可使硬度进一步降低。采用两段式退火和三段式退火可改善组织均匀性,显著降低硬度,而三段式退火工艺优于一段式退火和两段式退火工艺。In order to solve the problem of high annealing hardness of 2Cr12Ni4Mo3VNbN industrial bar,the effects of different annealing processes on the microstructure and hardness of 2Cr12Ni4Mo3VNbN blade steel were systematically studied.The results show that compared with twophase zone heating annealing and incomplete annealing,complete annealing has better annealing effect,the hardness is the lowest after annealing,and the hardness can be further reduced by furnace cooling.The two-stage annealing and three-stage annealing can improve structure uniformity and significantly reduce the hardness.The multi-stage annealing process is better than the one-stage annealing and twostage annealing with regards to hardness reduction through annealing.
