摘要	The effects of Co and Ti additions on the microstructures and compressive strength of the Ni-based superalloy Udiemt710 (U710) were investigated. The preliminary results showed that the Ni(3)Ti-type (eta) phase was observed in the alloys with low Co and Ti content; while a (Ni(x)Co(1-x))(3)Ti phase with a hexagonal structure was detected in the alloys with high Co and Ti content. The gamma ' ->eta ->( Ni(x)Co(1-0))(3)Ti phase transformation was discussed in terms of Co and Ti contents. The gamma ' morphology changed from spherical to cuboidal with increasing Co and Ti content. Compressive tests showed that the alloys with Co and Ti addition possessed higher yield strength than the base alloy, U710. The strength increase could be ascribed to solid-solution strengthening of the gamma and gamma ' phases as a result of the Co and Ti additions, and the higher volume fraction of gamma ' in the new alloys.
