摘要
大颗粒夹杂物对轴承钢的疲劳寿命有重大的影响。针对轴承钢非金属夹杂物的评价方法进行了比较和分析。利用高频超声波C型扫描法对轴承钢钢材试样进行检测,并利用金相法对超声波C型扫描法检测的结果进行验证。结果表明:高频超声波C型扫描法用于检测轴承钢中的大颗粒夹杂物是非常有效的。
Large inclusions have a significant impact on the fatigue life of bearing steel. The evaluation methods for inclusions in bearing steel were compared and analyzed. Bearing steel were tested by high frequence ultrasonic C-scan, and using metallographic method to validate the results. The results showed that the testing method of high frequence ultrasonic C-scan was effective for the testing of large inclusions in hearing steel.
