Abstract Scope Our study aims to produce titanium and titanium alloy components without involving melting and casting. One route is to turn the titanium sponge into titanium powder by a process such as hydrogenation and dehydrogenation (HDH) and use powder blending, compacting and powder compact forging and extrusion-forging to facilitate powder consolidation and forming to various shapes. In-situ alloying and composition homogenization also occurs rapidly during plastic deformation of powder particles. Titanium hydride powder can also be used, since in-situ dehydrogenation can occur during heating of the powder compact to the consolidation temperature. The residual hydrogen can assist formation of ultrafine structure which is beneficial to the mechanical properties. It has been found that good mechanical properties are obtained with Ti-6Al-4V(wt.%) and other alloys. This report will present the findings from our group in manufacturing high performance titanium alloy components by thermomechanical powder consolidation and discuss the underlying materials science principles.
