The addition of Al to Ti can be used to reduce the intrinsic cost of the material, decrease the density of the alloy, and increase the mechanical performance. This study is focused on evaluating the physical properties, microstructural evolution and mechanical behaviour of Ti-xAl alloys (where x = 1–6 wt%) in order to scientifically understand the strengthening mechanisms of the addition of Al to pure Ti manufactured via the conventional powder metallurgy route of cold uniaxial pressing plus solid state sintering. The addition of Al to Ti does not affect the compressibility of the alloy but changes the consolidation and densification of the alloy. The incremental addition of Al results in the progressive strengthening of Ti via the simultaneous contribution from substitutional solid solution and grain refinement strengthening which outdo the negative effect of the residual porosity.enThis is a submitted version of an article from the Journal of Alloys and Compounds. © 2020 Elsevier.low-cost titanium alloytitanium powder metallurgypress and sinterblending elementalhomogeneous microstructurestrengtheningscience & technologyphysical sciencestechnologychemistry, physicalmaterials science, multidisciplinarymetallurgy & metallurgical engineeringchemistrymaterials scienceinterdiffusiontemperaturediffusiondiffusiondiffusiondiffusiondiffusiondiffusiondiffusionJournal Article10.1016/j.jallcom.2019.1534471873-466940 Engineering4016 Materials Engineering4016 Materials engineering5104 Condensed matter physics
