| Abstract: | ZrC reinforced Zr41Ti14Cu12.5Ni10Be22.5 bulk amorphous matrix composites have been produced by reaction between added TiC and Zr in molten Zr-Ti-Cu-Ni-Be glass-forming allay and by copper mold casting method. The results of optical microscopy, X-ray diffraction, differential scanning calorimetry and scanning electron microscopy show that the reaction-induced crystalline ZrC particles with small size uniformly distribute in amorphous matrix. Compared with pure bulk amorphous alloy, the compressive strength and elongation of the composite are significantly improved. The mechanisms of in situ ZrC particles synthesis and strengthening are discussed. |
| Keywords: | Zr matrix amorphous composite in situ synthesis ZrC particle mechanical properties |
