摘要
就稀土元素铈(Ce)对铸态合金的组织、断口形貌、第二相分布、位错组态及压缩性能的影响进行了分析研究。结果表明,Ce不仅细化了晶粒,提高了合金的强韧性,而且还对其断口形貌和位错组态产生了明显的影响。
Research has been given for Ce's action on the microstructure,fracture textute,second-phase distribution,dislocation morphologyand the comp ression properties of as-cast Fe_3 Al alloys. The results showthat Ce not only has the fining function on the grains, but also has the obvious effect on the fracture texture and the dislocation morphology.
