摘要

为了控制残余奥氏体含量以获得更高性能的航空轴承钢

优化深冷处理工艺是有效的途径。研究深冷时间对经淬火、-75℃下深冷和回火处理后的低碳Co-Cr-Mo-Ni-W高合金钢组织和力学性能影响

结果表明:深冷回火后试验钢的组织主要为回火马氏体

同时还有一定量残余奥氏体和细小均匀分布在基体上的纳米碳化物;在2~6h范围内

随着深冷时间延长

由于残余奥氏体含量降低

回火马氏体板条细化

位错密度提高

纳米级碳化物数量增加且分布均匀化

强度显著提高

塑性逐渐降低;深冷时间超过6h后

残余奥氏体含量继续减小

位错密度增加

纳米碳化物尺寸长大

数量减少

强度和塑性均变化不大;试验条件下

深冷时间为6~10h时

获得了超高强度和良好的强塑性匹配

屈服和抗拉强度分别为~1690MPa和~1940MPa

延伸率为~14.3%。

Abstract

To achieve the superior performance of aerospace bearing steel by controlling the retained austenite content

the optimization of cryogenic treatment parameters is an effective approach.The microstructure and mechanical properties of a low-carbon Co-Cr-Mo-Ni-W high-alloy martensite steel after quenching

cryogenic treatment at -75℃ for different times and tempering are investigated.The results show that the microstructure of the martensite steel after cryogenic tempering contains the complex phases with tempered martensite

retained austenite and nano-carbides.As the cryogenic time increases from 2 to 6h

the strength of the steel significantly improves and its ductility reduces due to the refinement of tempered martensite lath and the decrease in residual austenite volume fraction

the increase in dislocation density and the increase in the quantity of nano-carbides with more uniform distribution.When the cryogenic time exceeds 6h

the strength and ductility of the steel change slightly because the retained austenite volume fraction decreases

the dislocation density increases and the nano-carbide sizes coarsen with the decrease in quantity.An excellent balance of strength and ductility

with the mean yield strength of about 1690MPa

the ultimate strength of about 1940MPa and the mean elongation of about 14.3%

is achieved for the steel after quenching

cryogenic treatment for 6-10h and tempering.
