摘要：

Nb-Nb5Si3 eutectic alloys with different Ta contents were prepared by arc melting in vacuum. The studies of the microstructure and compressive properties of the alloys showed that Ta mainly dissolved in Nb solid solution matrix. With increasing Ta content the amount of Nb5Si3 phase decreased, and Ta promoted the transformation of beta-Nb5Si3 to alpha-Nb5Si3. The addition of Ta is beneficial to enhancing the compressive strengths at room temperature and high temperature. In addition, the maximum value of compressive strength at high temperature was obtained for the composite with 5at.% Ta.
