✦ Synopsis

The crystallization kinetics of Ni x Ti 1 À x (x= 53.5, 48.1, and 42.9) alloy thin films have been investigated by means of differential scanning calorimeter under nonisothermal conditions. The onset crystallization temperature T x , crystallization peak temperature T p and effective activation energy E c of Ni x Ti 1 À x alloy thin films are found to depend on the average heating rate and thin films composition during the continuous heating. The effective activation energy and the frequency factor are determined by the Kissinger method. The effects of composition and heating rate for NiTi thin films on crystallization have been discussed in view of the mobility of atom cluster.
