ELECTRICAL PROPERTIES AND CRYSTALLIZATION OF Cu_(0.60)Ti_(0.40)METALLIC GLASS

The electrical properties and crystallization of Cu_(0.60)Ti_(0.40)metallic glass wereinvestigated by X-ray diffraction,DSC technique and electrical resistance measure-ment under isothermal and isochronal heating conditions.A negative temperaturecoefficient of electrical resistivity of the metallic glass Cu_(0.60)Ti_(0.40)is presented,andit becomes positive and increasing value in process of crystallization.Its crystal-lization is shown in two stages and in conformity with he J-M-A equationbasically.A good mutual couforment about the activation energies of crystalliza-tion was made with calculation by various methods.It seems that there is agreat potentiality in the increase of the stability of Cu-Ti metallic glass.
