摘要：

A joint of Zr55Cu30Ni5Al10 bulk metallic glass to crystalline material (Al-5Fe alloy) was achieved successfully by the pre-friction assisted diffusion bonding. This method employed the pre-friction process to break the oxide film of bulk metallic glass specimens. The average tensile strength was 58.42 MPa, which is much higher than CDB. The bulk metallic glass workpieces after joining retained the unique amorphous structure, indicating that thermal cycle, microscopic deformation and interface atomic diffusion caused no microstructural transformation of amorphous state. The pre-friction assisted diffusion bonding mechanism was proposed, which showed that the pre-friction process played a role of breaking the oxide film and providing a favorable diffusion bonding condition.
