| 摘 要： | 用Y—K—Na对M2高速钢进行复合变质处理,研究了变质处理对M2高速钢组织和性能的影响。结果表明,M2铸造高速钢经Y-K-Na复合变质处理后,组织明显细化,共晶碳化物由网状分布变为块状和团球状,冲击韧性提高70.7％,耐磨性也明显提高,各项力学性能接近锻造M2高速钢的水平。

| Abstract: | M2 high speed steel was modified by Y -K -Na.the effects of complex modification on the structures and properties of M 2 cast high speed steel has been researched. The results show that the structures of modified M2 cast high speed steel by means of Y -K -Na were obviously refined,network eutectic carbides were changed into spherical. After modification, the impact toughness was increased by 70. 7%, wear resistance was also increased,all mechanical properties of inoculation M2 high speed steel near to that of forging M2 high speed steel,the modified mechanism was also analyzed. |
