Abstract:
1. A method for fabricating a composition of Zr-rich bulk amorphous alloy, the method comprising: providing a weld member and a base, both the weld member and the base made of Zr-rich bulk amorphous alloy, the weld member comprising a main body and a weld portion disposed at an end of the main body, a thickness of the weld portion being less than that of the main body; the weld portion having a thickness of about 1.00 mm to about 1.30 mm; and welding the weld portion of the weld member to the base by a pulsed laser in a protective gas environment, wherein a maximum power of the pulsed laser exceeds or equals 3.5 kW, and a welding rate exceeds 2 mm/sec, thereby keeping a welding area of the weld portion and the base in an amorphous state.
