英文摘要	The low ductility and insufficient strength of the TiAl alloy are still two major obstacles for its applications. It was demonstrated that Ti5Si3 could improve the ductility of TiAl alloy, while it can't obviously improve the strength. In order to further improve the strength of Ti5Si3/TiAl composite to obtain TiAl materials with excellent strength and ductility, the effects of alloying elements (Cu, Zn, W and Mo) on the compression strength of the in-situ nano-Ti5Si3/TiAl composite were investigated in this work. With the addition of 2 at.% Me (Me = Cu, Zn and W, respectively), the compression true yield strength (sigma(y)(true)) of the composite increases from 613 MPa to 840, 660 and 706 MPa, respectively. Moreover, the addition of Zn results in the increase of the sigma(y)(true) with no obvious sacrifice of ductility. Finally, the 4 vol.% nano-Ti5Si3/TiAl-2Zn composite obtained the best comprehensive properties. Compared with the TiAl alloy, the sigma(y)(true), sigma(UCS)(true) and epsilon(f)(true) of the Ti5Si3/TiAl-2Zn composite increases by 195, 140 MPa and 2.6%, respectively.
