摘要
研究了淬火工艺 (包括奥氏体化温度、保温时间及冷却速度 )对KmTBCr2 6高铬铸铁的硬度和冲击韧度的影响。结果表明 ,淬火工艺对试样硬度有显著的并有规律性的影响 ,得到最高硬度的最佳奥氏体化温度为 980～10 2 0℃ ,最佳保温时间与试样的原始组织有关 ,不同淬火工艺的试样冲击韧度数据无明确的规律性。
The Effects of quenching process (including austenitizing temperature,austenization holding time and cooling rate) on mechanical properties of KmTBCr26 high chromium cast iron was investigated by measuring hardness and impact toughness.The results show that the quenching process has a remarkable influence on the hardness of the samples regularly.The optimal austenitizing temperature range which produce the highest hardness is 980～1020℃ and the optimal austenization holding time is related to the original microstructure of samples.The data of impact toughness of the samples treated by various quenching process is ruleless.
