| In this study an initial assessment of the composition -- microstructure -- property relationships in binary and ternary Ti -- based systems are made possible using LENS(TM) technology. Laser Engineering Net Shaping (LENS(TM)), a rapid prototyping, directed laser deposition methodology of additive manufacturing (AM) was used to create bulk homogenous specimens that are compositionally graded. Compositionally graded specimens were made possible by incorporating elemental blends of powder during the LENS(TM) process.;While there have been numerous studies assessing the influence of common elements (e.g., V, Mo, Al, and Cr) on the resulting microstructure in titanium alloys, other elements have been neglected. A systematic study of the Ti -- Fe -- Al ternary system based upon varying compositions of the eutectoid former, Fe with Al to stabilize the alpha and beta phases respectively has also been neglected. This research effort focuses on exploiting the LENS(TM) process by rapidly assessing the composition -- microstructure -- property relationships in a combinatorial approach for the Ti -- W, Ti -- Fe, and Ti -- Fe -- Al systems.;Compositionally graded specimens of Ti -- xW (0< x<40wt.%(14.79at.%)), Ti -- xFe (0< x<35wt.%(36.37at.%)), and Ti -- xFe -- yAl (0 |
