W6Mo5Cr4V2AI(又叫M_2AI)是近些年在W6Mo5Cr4V2的基础上发展起来的新型超硬型高速钢。W6Mo5Cr4V2AI钢与通用高速钢相比,经过热处理后,有较高的硬度(HRC65～69),在刃具的使用中能有效地提高耐磨性;热加工过程中在950～1150℃范围内有较好的热塑性;在金相组织中碳化物分布细小、均匀等特点。同时W6Mo5Cr4V2AI钢还存在容易氧化脱碳,淬火时晶粒大小不易控制等主要问题。本文仅是在W6M
W6Mo5Cr4V2AI (also called M_2AI) is a new type of super-hard high-speed steel developed on the basis of W6Mo5Cr4V2 in recent years. W6Mo5Cr4V2AI steel compared with general high-speed steel, after heat treatment, a higher hardness (HRC65 ~ 69), the use of cutting tools can effectively improve the wear resistance; thermal processing in the 950 ~ 1150 ℃ range of more Good thermoplastic; Carbide distribution in the microstructure of small, uniform and so on. At the same time there W6Mo5Cr4V2AI easy oxidation and decarburization of steel, quenching the grain size is not easy to control and other major issues. This article is only on the W6M
