The thickness is as twice as that achieved by the melt spinning technique in the corresponding period (the largest thickness of 65 mm). The crystallization was characterized by using a differential scanning calorimetry. The activation energies are calculated based on the Kissinger equation and the effects of the La, Ce, Pr and Nd on the glass forming ability of Al-based alloy are discussed in the paper.展开更多
