摘　　要：研究了稀土硅钙镁 (Re- Si- Ca- Mg)复合变质处理对铸态复相耐磨钢中夹杂物形态和性能的影响。结果表明 :复合变质处理可显著改变复相耐磨铸钢中夹杂物的形态和分布 。The influence of compound modification (Re Si Ca Mg) on the inclusions morphology and properties of dual phase cast wear resistant steel is investigated. It was proved that the compound modification can influence notably the morphology and distribution of inclusions in dual phase cast wear resistant steel, improving its impact toughness greatly.
