预退火热处理对非晶态Ni-P合金晶化动力学的影响

卢柯 , 王景唐

金属学报

本文研究了预退火热处理对非晶态Ni-P合金晶化过程动力学参数的影响,实验结果表明,在570K随着预退火热处理时间的增长,晶化温度T_x和T_p值、晶化过程表观激活能E_c值及等温晶化过程平均Avrami指数值都显著减小,而ΔT_(px)=T_p—T_x值增大。

The effect of pre-annealing treatment on the crystallization kinetics parameters of amorphous Ni-P alloys has been investigated.Experimental results showed that the crystallization tem- perature,T_p and T_x,the apparent activation energy,E_c,as well as the Avrami exponent for isothermal crystallization,n,decrease significantly,while ΔT_(px)=T_p-T_x increases with the elongation of pre-annealing time at 570 K.
