抄録

Dissimilar friction stir welding of Zr55Cu30Ni5Al10 bulk metallic glass (BMG) to pure Al was carried out at different welding conditions. Sound BMG/Al joints can be obtained at a rotation speed of 350 and 400 rpm. However, defects or crack may form in the stir zone when the rotation speed was either too low or too high. In the sound joints, a clear and straight BMG/Al interface was formed and no intermetallic compounds caused either by chemical reaction or crystallization from the amorphous phase can be detected within the entire stir zone. The hardness of Al side in the stir zone decreases with increasing of the rotation speed and is lower than that in the base material due to frictional heat input. The sound BMG/Al joints fractured in the heat affect zone of Al side and the tensile strength can reach about 91% of that of the base material.
