Pre-friction diffusion hybrid bonding of Zr55Cu30Ni5Al10 bulk metallic glass

► Pre-friction diffusion hybrid bonding was proposed to achieve a BMG/BMG joint. ► The pre-friction process broke the oxide film of BMG specimens during joining. ► No observable crystallization was detected by MF-XRD and TEM. ► Pre-friction diffusion hybrid bonding provided a route for the bonding of BMG.
