The rolling contact fatigue life, hardness, residual stresses and the amount of retained austenite of the specimens were measured.
测定了试样的接触疲劳寿命、硬度、残余应力和残余奥氏体量。
The presence of a certain amount of retained austenite improves the resistance to contact fatigue failure. The lath martensite has better resistance than the plate twin martensite.
金相组织对钢的接触疲劳寿命有重要作用：板条马氏体组织比片状马氏体组织抗接触疲劳性能好，适量的残余奥氏体可改善钢的抗接触疲劳性能。
The results show that polygonal ferrite, granular bainite and larger amount of stabilized retained austenite can be obtained after hot rolling.
结果表明，热轧后能够获得多边形铁素体、粒状贝氏体和大量稳定的残留奥氏体组织。
For high chromium cast iron with structure of preferred orientation, its retained austenite amount can be measured accurately by X-ray method of rotating and tilting specimen holder.
对有择优取向的组织来说，用旋转摆动的X射线法可准确测定高铬铸铁中残余奥氏体的含量。
The results show that, with the increase of holding temperature, the amount of bainite and retained austenite, the carbon concentration in retained austenite first increases and then decreases.
结果表明，随等温温度的升高，贝氏体、残余奥氏体的量以及残余奥氏体中碳浓度先增加后减少。
