EFFECT OF PRE-ANNEALING ON CRYSTALLIZATION KINETICS OF Cu-Ti GLASS
预退火处理对非晶Cu—Ti合金晶化过程动力学的影响

The crystallizatiin kinetics of the Cu_(40)Ti_(60) glasses, either as-quenchedor pre-annealed, has been studied by differential scanning calorimetery. The crystal-lization temperature, activation energy for crystallization and Avrami exponent werefound to be lowered by pre-annealing. Both activation energies of nucleation andgrowth of the amorphous Cu_(40)Ti_(60) alloys were obtained on the basis of experimen-tal results and theoretical analysis.
