摘要
Based on the thermal analysis, the influence of pulsing current on the glass transition and crystallizing ki- netics of Zr41.3Ti14.2Cu12.8Ni10.3Be21.4 bulk amorphous alloy has been studied. The obtained results show that after the Zr41.3Ti14.2Cu12.8Ni10.3Be21.4 bulk amorphous alloy was pre- treated by high-density pulsing current at low temperature, its glass transition temperature Tg, the initial crystallizing temperature Tx and the corresponding exothermic peak of crystallization Tpi were reduced. But the temperature range of supercooled liquid ?T=Tx?Tg is almost the same. The calculated results with Kissinger equation show that the ac- tivation energy of glass transition of the alloy pretreated is reduced significantly, while the activation energy of crystal- lization is basically unchanged. The influence of pulsing cur- rent on the glass transition and crystallization of the Zr41.3Ti14.2Cu12.8Ni10.3Be21.4 bulk amorphous alloy is believed to be related with the structure relaxation of the glass caused by the current.
