(Cu60Zr30Ti10)98Y2 bulk metallic glass(Φ4 mm×70 mm) was obtained successfully by copper mould cooling and spraying-casting,and some samples were isothermally annealed at temperatures of 473 and 623 K,which was lower than the glass transition temperature(Tg) for 1 h.Microstructure and properties of as-cast and annealed samples were studied.Crystallization phases(Cu10Zr7 and CuZr) were observed in annealed samples,and the species and fraction of these phases increased with increasing annealing temperature.Mic... 相似文献

采用铜模喷铸法制备了φ4 mm×80 mill的Cu60Zr30Ti10、(Cu60Zr30Ti10)98 Sn2和(Cu60Zr30Ti10)98Y2合金棒试样.用X射线衍射仪(XRD)和差式扫描量热仪(DSC)分析了三合金内部结构及热稳定性.结果表明:合金元素Y、Sn均能提高Cu60Zr30Ti10合金的非晶形成能力,但添加Y的效果更佳.所制备的φ4 mm(Cu60Zr30Ti10)98Y2合金棒为完全非晶结构,且其热稳定性高于另外两种合金;非晶态(Cu60Zr30Ti10)98Y2合金的显微硬度低于由晶相/非晶组成的(Cu60Zr30Ti10)98Sn2、Cu60Zr30Ti10合金,且在该系列合金中,随着析出晶相增多,合金显微硬度下降. 相似文献
