“…At room temperature, a lack of tensile ductility (0.6%) was observed in both longitudinal and transverse sections of the as-deposited samples. The authors further investigated the effect of heat treatments using the same Ti-47Al-2.5V-1Cr alloy 13 . However, the compositional inhomogeneity of the asdeposited samples were not completely removed after heat treating at 1125°C for 30 min.…”

“…Thus, ALM offers great potential to produce geometrically intricate components with major savings in time, material, and hence cost [3,4]. Some work has been devoted to developing ALM processes for titanium aluminide alloys [5][6][7][8][9][10][11]. Compared to other production techniques, the GTAW-based ALM process offers several advantages, including high material use efficiency, high performance full density deposition, and the capability to economically produce large components.…”

In this work, an additive layer manufacturing (ALM) process based on gas tungsten arc welding (GTAW) was used to produce simple 3-dimensional titanium aluminide components, which were successfully in-situ alloyed by separately delivering elemental Al and Ti wires to the weld pool. Investigations were conducted on the additively manufactured -TiAl based alloy to assess the influence of heat treatment on the microstructure evolution, phase transformations and some other basic properties. The results indicated that heat treatment promotes the formation of the phase. This microstructural change resulted in the reduction of the microhardness mainly due to the reduction of the hard, brittle 2 phase.
