W6Mo5Cr4V2高速钢硬度的影响规律,得到了最佳的交变磁处理参数,并对最佳参数下处理的高速钢组织进行了观察.结果表明：交变磁处理可使高速钢的硬度提高4．6 HRC；最佳的交变磁处理参数为磁场频率5 Hz,励磁电压30 V,磁化时间60 s,试样被测表面和磁力线在同一个平面上；磁场频率和励磁电压对硬度的影响最大,磁场方向和磁化时间的影响较弱；经最佳参数交变磁处理后,碳化物的分布更加均匀,且尺寸更小,从而使得高速钢的硬度提高.","authors":[{"authorName":"朱涛","id":"bfe5be85-6bf8-4d6c-901a-a2e314c07cf7","originalAuthorName":"朱涛"},{"authorName":"刘政","id":"a5927dde-1f0c-46f2-92fd-dab6aae5bf72","originalAuthorName":"刘政"},{"authorName":"邓可月","id":"a7173e99-4961-4923-9324-e993421ba69d","originalAuthorName":"邓可月"},{"authorName":"<span
