摘要

采用差热分析(DTA)和x射线衍射(xrd)研究了快速淬火Al65Ni10Si25合金在加热和等温退火过程中的组织演变。研究了组织从淬火态向纳米晶态转变的过程。在较宽的温度和时间间隔内观察到六方h相的发生。结果表明，在403 ~ 463 K等温退火5小时后，亚稳h相未发生分解。

Structure Investigation of Rapidly Quenched Al65Si25Ni10 Amorphous Alloy After Izotermal Annealing

Structure evolution of rapidly quenched Al65Ni10Si25 alloy under heating and isothermal annealing was investigated using DTA and X-ray diffraction methods. The process of structure transformation from the as-quenched state into a nanocrystalline state has been studied. The occurrence of hexagonal H-phase was observed within wide temperature and time interval. It was shown that the metastable H-phase has not decomposed after isothermal annealing during 5 hour at temperatures 403 – 463 K.
