Joining of Zr₄₁Be₂₃Ti₁₄Cu₁₂Ni₁₀ Bulk Metallic Glasses by a Friction Welding Method

Abstract

In order to establish metallurgical bonding technology of bulk metallic glasses, friction welding of Zr₄₁Be₂₃Ti₁₄Cu₁₂Ni₁₀ bulk metallic glass with a wide supercooled liquid region and high glass forming ability has been tried. The Zr₄₁Be₂₃Ti₁₄Cu₁₂Ni₁₀ bulk metallic glass has successfully welded to the same bulk metallic glass together. Moreover, the effects of friction-welding conditions such as friction time, rotational speed and upsetting pressure have been investigated under a wide range of conditions, no crystallization and no defects were observed in the interface.
