【 摘 要 】

Dual amorphous phase bulk metallic glasses (DAPBMGs) are a new class of bulk metallic glasses (BMGs) containing several amorphous phases in order to bring together all the favorable properties of each phase. A Fe/Zr dual phase bulk metallic glasses of cylindrical form with the diameter of 10 mm and 5 mm in height, were successfully prepared by hot-pressing of Fe - based and Zr - based glassy alloy powder at different mixing times. The samples obtained were structural investigated by X-Ray diffraction and mechanically characterized by hardness and compression tests. It was found that increasing the mixing time of powders leads to a decrease in hardness and mechanical compressive strength.
