Abstract Phase equilibrium of Nb–Si–X ternary alloys (X = Zr, Ta, Al) was predicted by thermodynamic calculations. Microstructure characterization and phase identification have been performed to investigate the phase equilibrium and validate the prediction. High-temperature compression tests were performed to evaluate the mechanical properties. All alloys exhibited ssNb, Nb 5 Si 3 , and Nb 3 Si phases. Zr addition increased strength at both room and elevated temperatures. The alloy with large primary silicide islands exhibited a higher 0.2 pct proof stress.
用热力学方法预测了Nb-Si-X三元合金(X = Zr, Ta, Al)的相平衡。通过微观结构表征和相识别来研究相平衡并验证预测结果。通过高温压缩试验对其力学性能进行了评价。所有合金均表现出ssNb、Nb 5si3和Nb 3si相。Zr的加入提高了室温和高温下的强度。具有较大原生硅化岛的合金具有较高的0.2%抗应力。
