The results of creep tests in the bending mode at 1150 – 1200°C for the Nb – Si – X alloy (X = Mo, Ti, Hf, Zr, Cr, Al) after hot isostatic pressing and after induction melting in the mode of directed crystallization are analyzed. It was shown that the creep rate of powder alloys is an order of magnitude higher than the creep rate of an alloy with a directed structure, which is related to the microstructural features of the alloy and the type of silicide formed in its structure. In all the alloys tested, the short-term bending strength at 20°C weakly depends on their composition and method of fabrication, while at 1300°C the alloy with a directed structure has the highest strength.

多组分 Nb – Si – X (X = Mo, Ti, Hf, Zr, Cr, Al) 系合金的高温变形在 Hip 后和在定向结晶模式下感应熔化后

Nb-Si-X 合金（X = Mo、Ti、Hf、Zr、Cr、Al）在 1150-1200°C 弯曲模式下热等静压和感应熔炼后的蠕变试验结果分析了定向结晶。结果表明，粉末合金的蠕变速率比具有定向结构的合金的蠕变速率高一个数量级，这与合金的显微结构特征和在其结构中形成的硅化物类型有关。在所有测试的合金中，20°C 下的短期弯曲强度微弱地取决于它们的成分和制造方法，而在 1300°C 下，具有定向结构的合金具有最高的强度。
