摘要：
Zr-Ti-Cu-Ni-Be-Fe bulk metallic glasses and metallic glassy matrix composites were produced by water quenching method. The effect of Fe addition on glass forming ability, hardness, magnetic susceptibility and thermal stability of the alloys was investigated. It was found that the glass forming ability and the properties of the alloys were sensitive to Fe content. A single amorphous phase was obtained in the alloys up to 8 at%Fe addition. These bulk metallic glasses exhibited high thermal stability, wide super-cooled liquid region, and anomalous magnetic susceptibility chi versus temperature in the supercooled liquid region. Metallic glassy composites consisting of nanocrystalline FeZr2 particles were obtained in the alloys with more than 10 at%Fe addition.
