摘　　要：文章综述了近年来高品质齿轮钢的研究进展,包括高质量稳定性齿轮钢、高温渗碳齿轮钢以及超长寿命齿轮钢等方面,重点在不大于4HRC窄淬透性带宽控制技术、960℃以上高温渗碳晶粒长大控制技术以及10^(9)周次超高周疲劳破坏机理及控制技术等方面,为高品质齿轮钢的开发及应用奠定了基础。The paper overviews the rescarch progress in high quality gear steels in recent years,such as the gear steels with high quality stability,high-temperature carburized gear steels and gear steels with ultra-long service life,centering on the control techniques for narrow hardenability width less than 4HRC,grain growth under high temperature carburizing over 960℃ and the failure mechanism of 109 ultra-high cycle fatigue,which all together has laid a foundation for the development and application of high quality gear steels.
