  • COMPOSITION OF AMORPHOUS ALLOY AND METHOD FOR FABRICATING THE SAME
    Publication number: 20120199251
    Abstract: A composition includes a base and a weld member welded to the base to form a weld area. Both the weld member and the base are made of Zr-rich bulk amorphous alloy. The weld member includes a main body and a weld portion disposed at an end of the main body. A thickness of the weld portion is less than that of the main body. The weld portion has a thickness of about 1.00 mm to about 1.30 mm, and the weld area of the composition is in an amorphous state.
