马氏体－贝氏体基体球墨铸铁的研究与应用

Study and Application of Martensite-Bainite Ductile Iron

介绍了马氏体－贝氏体基体球墨铸铁的性能、生产工艺、成本及应用，并与现行使用的抗磨材料进行对比。马氏体－贝氏体基体球墨铸铁的抗磨性能较好、破碎率低、生产工艺简单、适用范围广，是一种较好的抗磨材料。

A type of martensite-bainite ductile iron is introduced. Compared with other wear-resistance materials,M-B ductile iron is of better properties of wear-resistance and toughness,With its simple manufacturing and lower factory-cost and wider range of application,M-B ductile iron is an ideal new wear-resistance material.
