【摘要】 本文研究了20CrMnTi钢碳氮共渗后淬火油温度对接触疲劳寿命的影响。结果表明,经较高油温淬火的试样中的残留奥氏体具有较高的稳定性,这是接触疲劳寿命随淬火油温的升高而提高的主要原因。更多还原

【Abstract】 This paper deals with the influence of the quenching oil temperature on the contact fatigue life of the carbo-nitrided 20 CrMnTi steel. The results showed that the higher is the temperature of quenching oil, the higher is the stability of the retained austenite in the sample. This is the main cause that the contact fatigue life is improved with the increase of quenching oil temperature.更多还原
