金属玻璃的形变与结构缺陷

金属玻璃的形变与结构缺陷 NON-HOMOGENOUS DEFORMATION AND STRUCTRE DEFCTS OF NON-GRYSTALLINE Fe 40 Ni 40 P 12 B 8 ALLOY 桂嘉年 first-author 夏伍戎 杜风牡 王少阶 王子孝 本文用扫描电镜、示差扫描热分析、正电子湮灭谱及低频扭摆内耗法研究了急冷Fe 40 Ni 40 P 12 B 8 金属玻璃条带在室温下的形变结构,并探讨其中的结构缺陷。尝试用旋错（Disclination）模型对其形变行为作出定性解释。 The Structure of non-homogenous deformation at room temperature of non-crystalline Fe 40 Ni 40 P 12 B 8 alloy was investigated by means of scanning electron microscope、differential scanning calorimeter、positron annihilation spectroscopy and internal friction measurement. The structure defects were discussed and a disclination model was proposed to explain the mechanical behaviours. 1983-02-01 2021-04-01 2
