An alternative method to manufacture Ti alloys from particulate materials
Ti alloys are the ideal material fora great range of applications but their industrial implementation is hindered by current technological and manufacturing limitations. This work presents the scientific development of an emerging alternative route to manufacture Ti alloys from particulate materials. Experimental evidences to show that the proposed manufacturing route, which takes advantage of the benefits of particulate processing, permits to obtain structurally sound Ti alloys using much shorter production routines removing some of the technological and manufacturing limitations hindering the use of Ti alloys in engineering applications are presented. It is found that the relative density increases with the sintering temperature reaching values around 93% and dissolution of the alloying elements is complete. The mechanical properties of the produced representative blended elemental alpha +/- beta Ti alloy also increase with the temperature reaching a maximum ultimate tensile strength of 850 MPa.
