| Abstract Scope |
A novel bainitic titanium alloy system has been designed specifically for additive manufacturing (AM). The Ti-xCu-yFe alloys take advantage of constitutional supercooling to suppress the growth of large columnar grains usually associated with AM Ti alloys. The bainitic microstructure shows refined α-phase within a matrix of β-phase. The intermetallic Ti2Cu forms prevalently on the edge of the α-phase and within the β matrix. The high strength of these materials in the as-built condition is attributed to the high prevalence of fine α-phase and Ti2Cu particle as well as significant solid solution hardening. This work demonstrates a viable way to fabricate structural components with unique and excellent properties using low-cost elemental powders with AM. |
