Abstract
The Zr 57 Al 10 Nb 5 Cu 15.4 Ni 12.6 bulk metallic glass-forming alloy is reinforced with tungsten fiber. Cylindrical samples up to 6.3 mm in diameter and 7cm in length have been synthesized using melt infiltration casting method. The structure and microstructure of the composites processed in typical conditions were analyzed by x-ray diffraction and scanning electron microscopy. The suitable interface reaction and fully amorphous matrix can only be obtained through the combination of a suitable infiltration temperature and time. The processing conditions were more rigorous compared to those of making Zr-Ti-Ni-Cu-Be matrix composite due to intermetallic compound nucleation when exposed to the tungsten fibers. A technique map, including infiltrating temperature and time is presented in this paper.
