| Abstract: | By adding Si to Zr-Fe-Cu alloy, amorphous/crystalline Zr-based composite alloy rods with a diameter of 3.0 mm were prepared by a copper mold suction casting method in water cooling crucibles. The microstructure and mechanical properties of Zr-based alloys were studied by X-ray diffraction （XRD）, microcomputer-controlled electronic universal test machine and scanning electron microscopy （SEM）. The results revealed that the microstructure, glass forming ability, mechanical properties and fracture morphologies of Zr-Fe-Cu alloy change greatly with the content of added Si. In addition, strength and plasticity of the alloys can be improved with added Si. |
