Abstract
There were many techniques of joining two or three materials. A new metallic liquid jointing technique which enables the joint of Zr 55 Cu 30 Ni 5 Al 10 bulk glassy alloy without any crystallization is very useful to produce a large bulk metallic glass. Molten alloy streams with high velocity are generated by ejection of alloy liquid through two nozzles at different sites. The jointed region has nearly the same structure, thermal stability and mechanical properties as those for the original glassy Zr 55 Cu 30 Ni 5 Al 10 alloy. The successful joint method can produce the large glassy Zr 55 Cu 30 Ni 5 Al 10 rod of 600mm in length and 3 mm in diameter.
