Abstract The effect of Nb content on the y'-phase precipitation-hardened Ni-Cr-Al-Ti base superaUoy has been investigated. Results show that a moderate addition of Nb could improve both strength and ductility of the superaUoy at room and high temperatures. It was ascertained that such improvement on the strength and ductility is made principally after the strengthening Y'-phase and the grain refinement respectively.
