  of the addition of 0.3%, 0.7%, 1.0%W (mole fraction) on the microstructure and mechanical properties of high-Nb TiAl alloy were studied. The results show that the W alloying doesn’t change the alloy solidification path, has no effect on the room temperature phase composition of high-Nb TiAl alloy. With the increase of W content, the segregation degree of Nb and Al element is enhanced......
