对采用射流成形方法制备的Ｚｒ５２．５Ｎｉ１４．６Ａｉ１０Ｃｕ１７．９Ｔｉ５块体玻璃合金进行等温退火，利用Ｘ射线衍射和ＳＥＭ及ＴＥＭ分析了块状玻璃态合金等温晶化时相转变及组织转变．实验表明，近玻璃转变温度Ｔｇ退火，组织仅发生部分晶化，近晶化温度Ｔｘ和高于Ｔｘ（７０３—７２３Ｋ）退火后，合金完全晶化，组织为Ｚｒ２Ｎｉ０．６７Ｏ０．３３＋ＺｒＡＩ（少量）＋Ｚｒ２Ｃｕ（量）；更高温度（７５３—８２３Ｋ）退火后，晶化组织中ＺｒＡＩ和Ｚｒ２Ｃｕ数量相对增多，完全晶化后样品由纳米晶组成
Isothermal annealing of Zr52.5Ni14.6Ai10Cu17.9Ti5 bulk glass alloy prepared by jet forming method was carried out. X-ray diffraction, SEM and TEM were used to analyze phase transformation and microstructure transformation of bulk glassy alloy during isothermal crystallization. Experiments show that the near-glass transition temperature Tg annealing, the organization only partial crystallization, the crystallization temperature Tx and higher than the Tx (703-723K) annealing, the alloy completely crystallized, the organization Zr2Ni0.67O0.33 + ZrAI (small amount) + Zr2Cu (Amount). After annealing at higher temperature (753-823K), the amount of ZrAI and Zr2Cu in the crystallized structure increased relatively. After the complete crystallization, the sample consisted of nanocrystalline
