Titanium aluminide (mainly TiAl) based intermetallic alloys have superior mechanical properties up to 800 C and are much lighter than the currently used nickel superalloys. They have been developed for turbine engine applications in the aerospace, automobile and energy industries. Because of the inherent brittleness of TiAl, conventional manufacturing requires specially designed post processing, which is not cost and time effective. Additive manufacturing (AM) is considered as an alternative production technique, that can replace the conventional process. AM facilitates printing of complex TiAl components directly from alloy powders. Solid-state transformations (SST) associated with the uni..
