| Abstract |
| To increase the toughness of amorphous alloys and to verify the processibility of their composites, Zr41.2Ti13.8CU12.5Nil0.0Be22.5 composites reinforced with continuous fibers of tungsten and SUS304 have been developed by the liquid pressing process. The thermal stress of fiber/matrix interfaces and the cooling behavior of composites during the process were predicted. Observation by X-ray diffraction and scanning electron microscopy showed the amorphous state of matrices, which confirmed the process feasibility of amorphous alloy composites. In order to identify the toughness enhancement, compression tests have been conducted. SUS304 fiber composites resulted in the drastic increase of compressive strain (over 40%) compared to that of unreinforced Zr41.2Ti13.8CU12.5Ni10.0Be22.5 alloy. |
