马氏体基体 meaning in Chinese

martensitic matrix

Abstract : the structure and the properties of the grinding ball made of the composite cast iron have been researched in this paper . the result indicates that added trace boron and a proper quantity copper to this kind of composite cast iron can increase its quench - hardening ability , and raise its hardness and impact toughness
文摘:研究了一种复合铸铁磨球的组织和性能，结果表明，化学成分和淬火工艺对这种复合铸铁磨球的组织和性能有很大影响，微量的硼和适量的铜可以明显地提高磨球的淬透性，经过余热淬火得到贝氏体或马氏体基体组织，从而提高磨球的硬度和冲击韧性。
The results show that the solidification microstructure of high speed steel fe - 2 % c - 4 % v - 4 % mo - 5 % cr - x % w ( wt ) contains of martensite , retained austenite structure , and mc , m6c , m2c carbides , and mc / m2c complex carbides by xrd , sem and metallographs . most of the mc carbides locate in the cell and other carbides distribute along the boundary of the cell
结果表明：经金相组织观察、 x射线衍射和扫描电镜分析， fe - 2 c - 4 v - 4 mo - 5 cr - x w合金系高速钢凝固组织包含马氏体基体、残余奥氏体及各种类型的碳化物如mc型碳化物、 m _ 2c型碳化物、 m _ 6c型碳化物和mc m _ 2c类型复杂碳化物，大部分mc型碳化物分布于晶粒内部，其它类型碳化物则沿晶界呈网状分布。
