CRYSTALLIZATION KINETICS OF CU3TI2 FORMING FROM CU60TI40 GLASS - CONTINUOUS HEATING EXPERIMENTS IN XRD AND DSC

Amorphous to crystalline transformation in Cu60Ti40 alloy has been stu died under conditions of constant heating rate experiments, using XRD and DSC. In the high temperature XRD experiment, the transformation ha s been monitored continuously as the integrated X-ray intensity corres ponding to a chosen reflection from one of the two crystalline product s forming at close by temperatures. Differentiation of the curve thus obtained gives the transformation rate curve which passes through a ma ximum, From the peak shift with heating rate, the activation energy fo r the formation of Cu3Ti2 crystalline phase has been obtained. The res ults have been compared with those obtained by DSC.
