通过重复冷轧 Ni/Ti 包覆粉末制备出 Ni/Ti 多层。使用 XRD,SEM,TEM 和磁性分析方法研究了该多层由等温退火导致的固态非晶化反应。运用瞬态形核模型首次在 Ni/Ti 系统中研究了非晶层生长的三类定量关系,即①临界厚度与等温温度②临界退火时间与等温温度③温度-时间-转变关系。上述的定量研究可为三维大尺寸的研制提供理论上的指导。 Ni / Ti multilayers were prepared by repeated cold rolling Ni / Ti coated powders. The XRD, SEM, TEM and magnetic analysis methods were used to study the solid-state amorphization reaction of the multilayer by isothermal annealing. For the first time, three kinds of quantitative relationships of amorphous layer growth were studied in the Ni / Ti system using the transient nucleation model: ① critical thickness and isothermal temperature ② critical annealing time and isothermal temperature ③ temperature-time-transformation relationship. The above quantitative research can provide theoretical guidance for the development of three-dimensional large size.
