| 摘 要： | 研究六面锻造和液氮处理对Cr12Mo1V钢耐磨性能的影响。结果表明，六面锻造加余热淬火处理，使钢中碳化物级别降低1～2级，使钢的奥氏体晶粒度降低2级，从而提高了耐磨性。淬火后再经液氮处理，既降低残余奥氏体含量，提高硬度，又降低钢中残余应力，明显地提高了钢的耐磨性。

| Abstract: | The effects of forging in six directions and cryogenic treatment on the awear resistance of Cr12Mo1V steel are studied in this paper.The results indicate that:(1)The forging in six directions plus quenching after forging causes the eutectic carbide to reduce by 1~2 grades and the crystal thin by 2 grades;(2)Cryogenic treatment significantly reduces the amount of surviving austenite and the residual stress in steel.These explain well the remarkable increase of the wear resistance of Cr12Mo1V steel. |
