摘要
稀土硼的变质作用能有效地增加中碳马氏体钢的强韧性,而硬度不变,主要是细化晶粒、改善组织、净化钢液和控制钢中夹杂物的形状、大小及分布。
The toughness and strength of the medium carbon martensite steel can be effectively increased by Rare Earth-Boron modification, but the hardness remains nochange. The main reasons: refin ing grains,improving microstructures,cleaning molten steel, controlling the morphology,size and distribution of inclusions.
