摘要 | The glass formation under high-energy ball milling was investigated for a (Ti0.33Zr0.33Hf0.33)(50)(Ni0.33Cu0.33Ag0.33)(40)Al-10 high-order alloy system. For comparison, the glassy ribbon with the same composition was prepared using melt-spinning (MS) method as well. Structural features of. the samples were characterized using X-ray diffraction, ransmission electron microscopy and differential scanning calorimetry. Mechanical alloying (MA) results in a formation of glassy alloy similar to that obtained by MS. But, the glass formation is incomplete and a small amount of unreated crystallites smaller than 30 nm in size still remains in the final product. Like the melt-spun glass, the ball-milled glassy alloy also exhibits a distinct glass transition and a wide supercooled liquid region of about 80 K. Crystallization of the glassy alloy is a two-step process, regardless of the synthesis routes. After the primary crystallization is completed, the remaining amorphous phase shows a detectable glass transition and a large supercooled liquid region of about 100 K. |
