The use of alternative materials in automotive production can lead to both significant weight reductions and oftentimes functional improvements as well. Titanium and its alloys have unique properties that enable its use in the aerospace industry like its high strength-to-weight ratio, good resistance to many corrosive environments, and can be used over a wide range of temperatures. Despite these high expectations and the numerous advantages of titanium materials, their use has always failed just for a single reason: price. Powder metallurgy (P/M) of titanium and Ti-based alloys may lead to the obtainment of components having weak-to-absent textures, uniform grain structure and higher homogeneity at lower costs (a necessary prerequisite to expand the use of titanium and its alloys) compared with conventional wrought products. In this work Ti-6Al-4V and Ti-48Al-2Cr-2Nb (γTi-Al) were produced by P/M in order to expand the application in automotive area.
