【摘要】 采用气相蒸发法制备纳米量级的Ｎｉ－Ｔｉ非晶合金粒子，研究了各种因素对Ｎｉ－Ｔｉ纳米非晶合金粒子形成的影响，并用透射电子显微镜，高分辨电子显微镜，Ｘ射线衍射仪和能谱等多种手段对纳米非晶合金粒子进行了表征．结果表明，当粒子成分在共晶区Ｎｉ（４０）Ｔｉ（６０）附近时，容易形成非晶；较低惰性气体压力和较高蒸发温度有利于Ｎｉ－Ｔｉ纳米非晶粒子的形成．更多还原

【Abstract】 Parameters of gas evaporation method to prepare the nano-particles of amorphous Ni-Ti alloy have been investigated. The particles obtained were characterised by TEM, HREM, XRD and EDAX. It seems to form easily the amorphous nano-particles under some lower pressure of the inert gas and higher evaporating temperature within a composition range near Ni40Ti60 eutectic.更多还原
