提高中碳马氏体耐磨铸钢强韧性的研究

【摘要】 通过加入稀土来强化中碳马氏体耐磨SiMn铸钢,提高该钢的韧性。讨论了稀土对该钢中夹杂物形态和数量响,认为强韧化中碳马氏体钢的有效方法是添加微量元素—一定量的稀土。更多还原

【Abstract】 By adding some rare earth to the medium carbon martensite SiMn cast steel,it can improved the toughness of the steel.This paper will discuss the effects of the inclusion shape and amount of steel.We think the available way which strengthen medium carbon martensite steel’s tenacity is to add rare earth-trace element.更多还原
