摘要
铈对ZA27合金组织和性能的影响傅旭力,刘友鹏(东南大学材料科学与工程系,南京210018)ZA27合金是目前国内外迅速发展的新型材料[1~4].但由于该合金的凝固温度范围宽,容易形成偏析、缩松等缺陷,使该合金的延伸率、冲击韧性偏低[3],这在许多应...
The influence of Ce on the mechanical and wear resisting properties of ZA27 alloy are stud-ied under condition of directional solidification.The results indicate that if the melt is modified withCe,the ductility and wearability of ZA27 alloy can be improved on。When ZA27 contains a smallamount of iron and then is treated with Ce,the better wear resistance can be obtained without any sub-stantial losses of other mechanical properties。
