摘要：

The influence of the addition of 2.3 at.-% Y and of 0.8 at.-% Zr + 0.2 at.-% Y on the properties of TiAl43Nb4Mo1B0.1 (TNM-B1) titanium aluminide alloy is investigated. Energy-dispersive X-ray spectroscopy analysis shows that the Y content of the beta, gamma, and alpha(2) phases is low, and nearly all of the Y is in the Al2Y phase. The Zr content in the alloy phases is the same as that in alloy. Tensile tests show that Y addition decreases tensile strength and elongation, but only minor effects on these properties are observed after the addition of Zr and Y. It is shown that the addition of Y leads to a decrease in the heat resistance of TiAl43Nb4Mo1B0.1 alloy at 900 degrees C.
