| 摘 要： | 设计了一种用廉价的硼元素部分（或全部）取代普通高速钢轧辊中价格昂贵的合金元素的轧辊。借助光学显微镜（OM）、X射线衍射（XRD）、扫描电镜（SEM）和透射电镜（TEM）等方法对高硼高速钢轧辊铸态组织进行研究。结果表明：高速钢轧辊铸态组织主要由马氏体基体和少量的残余奥氏体以及M23（B,C）6,M3（B0.7C0.3）和（W,Mo）2（B,C）碳硼化合物组成,基体显微硬度达到820～950 HV,轧辊的铸态硬度大于64 HRC。

| Abstract: | A low alloy high speed steel(HSS),containing boron,which could be used for roll steel,was successfully designed.Microstructure of the as-cast low alloy HSS roll was investigated by means of optical microscopy(OM),X-ray diffraction(XRD),scanning electron microscopy(SEM)and transmission electron microscopy(TEM).Its hardness was tested.The results show that the microstructure of the low alloy HSS roll containing boron consists of lath martensite and a small amount of retained austenite,borocarbides of M23(B,C)... |
