摘要: The non-isothermal crystallization kinetics of Mg61Zn35Ca4 glassy alloy prepared via melt-spinning were studied by using isoconversion method. crystalline characterization was examined X-ray diffraction. Different scanning calorimeter used to investigate the at different heating rates (3-60 K/min). calculated value Avrami exponent obtained Matusita method indicated that transformation for is a complex process nucleation and growth. Kissinger-Akahira-Sunose activation energy. energy varies with extent hence temperature. Sestak-Berggren model describe kinetics.
