摘要

The crystallization parameters of new easy glass forming Mg₇₅Ni₂₀Nd₅ and Mg₆₅Ni₂₀Nd₁₅ alloys with large supercooled liquid regions were determined isothermally by DSC. The Avrami exponent n as well as the associated activation energy E for crystallization were found to be different at heating temperatures near the glass transition temperature T_g and crystallization temperature T_x. This result indicates a difference in crystallization mechanism for these glasses in these different temperature ranges.
