| 摘 要： | 研究了三种丝杠钢的接触疲劳性能。利用TEM和背散射Mossbauer谱研究了三种钢在接触疲劳前后的显微组织结构;测量了接触区中心线下显微硬度随层深的变化。结果表明:接触应力诱发A_R→M相变,并导致一定深度的冷作硬化。讨论了诱发相变和冷作硬化对接触疲劳性能的影响。

| Abstract: | Investigations were made by TEM, back scattering Mossbauer spectra,etc. to study the contact fatigue properties, to observe the microstructures beforeand after contact fatigueing and to measure the microhardness distribution beneaththe contact surface of the three leading screw steels. The martensitic transformationof retained austenite and the cold worked hardening are induced by contact stress.The effect of induced transformation and cold. worked hardening on the contactfatigue properties has been discussed. It is believed that the contact fatigue proper-ties of the steels may be improved by means of increasing the austenite content, yettheir hardness does not reduce so much. |
