根据前文提出的晶化微观机制,导出了非晶态合金晶化过程中晶体长大速率的数学表达式。用此表达式圆满地解释了Nunogaki、Heimendahl以及我们的实验结果,并能模拟原位加热时非晶态Ni-P合金薄膜晶化过程中的晶体长大过程及晶体长大尺寸与时间的关系。根据此表达式,讨论了影响晶体长大速率的因素,如温度、时间及非晶态合金的微观结构等。
A mathematical expression of the crystal growth rate during crystalli-zation of the amorphous alloys was derived from the micromechanism of crystalli-zation newly developed by the authors. Thus, the satisfactory explanation of theexperimental results obtained by Nunogaki et al., Heimendahl et al. and the authorsmight be found. It seems also to be modelled with the expression for the crystalgrowth and the crystal size influenced by time during the crystallization of amor-phous Ni-P alloy foil at in situ heating. Based on the expression, the factors influ-encing the crystal growth rate, such as temperature, time and microstructure of am-orphous alloys, have been discussed.
