摘要
本文介绍了高温补充回火对热处理后不合格活塞头力学性能的影响 ,结果表明 :降低回火温度对热处理后不合格活塞头进行补充回火 。
This paper has introduced the effect of high temperature additional tempering on the mechanical properties of the heat-treated substandard piston-head.The results show that the substandard piston-head's ductility and impact toughness can be improved by additional tempering with low temperature.
