چکیده انگلیسی
The crystallization behavior of Ca50Mg22.5Cu27.5 metallic glass in supercooled liquid has been examined using a technique of differential thermal analysis. Crystallization mechanism of the alloys during isothermal annealing in supercooled liquid was analyzed using the Johnson–Mehl–Avrami (JMA) equation. The experimental data of the isothermal crystallization was interpreted by the JMA model. The Avrami exponents for the ribbon and bulk alloys are 2.5 ± 0.5 and 2.3 ± 0.3, respectively. Both values of the Avrami exponent suggested that the crystal growth is controlled by a long-range diffusion process. The scaling law for crystallization of the alloys was also examined.
