EFFECT OF PRE-ANNEALING ON CRYSTALLIZATION KINETICS OF AMORPHOUS Ni-P ALLOYS

The effect of pre-annealing treatment on the crystallization kinetics parameters of amorphousNi-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 forisothermal crystallization,n,decrease significantly,while ΔT_(px)=T_p-T_x increases with theelongation of pre-annealing time at 570 K.
