Dissimilar welding of Zr41Be23Ti14Cu12Ni10 bulk metallic glass and stainless steel

The electron beam welding of 2 mm thick Zr41Be23Ti14Cu12Ni10 bulk metallic glass (BMG) plate to stainless steel was investigated. The BMG was welded to specially designed stainless steel with an electron beam acceleration voltage of 60 kV, a beam current of 20 mA, a welding speed of 66 mm s−1 and an electron beam irradiation position (dw) of 0.2 mm. The flexural strength of the welded joint (642 MPa) was higher than the yield strength of the stainless steel (478 MPa).
