Isothermal Crystallization Behavior of Cu₄₂Zr₄₂Al₈Ag₈ BMG Investigated with Electrical Resistance Measurement

Abstract:

The isothermal crystallization behavior of the Cu₄₂Zr₄₂Al₈Ag₈ bulk metallic glasse (BMG) was studied by the electrical resistance method. The increasing local activation energy means that the crystallization of the Cu₄₂Zr₄₂Al₈Ag₈ BMG becomes more and more difficult during the isothermal process. In the stage that the crystallized volume fraction falls into the range of 25–85%, the crystallization of the Cu₄₂Zr₄₂Al₈Ag₈ BMG is diffusion-controlled growth with a decreasing nucleation rate.
