三元合金体系金属玻璃成分区域的初步预测
摘要
The glass forming ability of binary alloy metallic glass was calculated and evaluated by using thermodynamics method. The Zr-Cu-Al ternary alloy glass formation component range was estimated by using the 1/χ parameter of the proposed early. Early results proved, when 1/χ>1.28, the component range of Zr-Cu-Al ternary alloy roughly coincides with the component range of Zr-Cu-Al ternary alloy obtained through abundant experiment. On that basis, the 1/χ value of the Nd-Al-Fe and Nd-Al-Co ternary alloy was calculated and about 1/χ>2.7 and 1/χ>2.9, respec- tively. Compared with Earlier Studies result, it knows that 1/χ can effectively make true Nd-Al-Fe and Nd-Al-Co ternary alloy metallic glass formation approximate range. At last, it regards as that the 1/χ value can effectively make true the glass formation component approximate range of ternary alloy metallic glass.
