“…The investigation of the mechanisms behind the reduction of the melting point due to Zr additions was beyond the scope of this work. However, in contrast to the additions of Cu [28], Ni [29] or iron [30], in which liquid phase is present due to a eutectic reaction, it seems that Zr additions systematically decrease the melting point of the quaternary alloys. This could also lead to liquid phase formation at lower temperatures compared to the reference alloy.…”

“…Titanium aluminide (TiAl) alloys with high strength-to-density ratio and excellent resistance to creep and oxidation at high temperature are structural materials for various applications [110]. The manufacture of TiAl components through different PM processes including MIM [62-64, 111, 112], has been considered for many years due to the alloy's limited ductility and inadequate hot workability to be manufactured through conventional casting, hot working and machining processes [113].…”

“…Ti–48Al–2Cr–2Nb is regarded to be a typical Gamma titanium aluminum alloy, that is, suitable for use as high temperature structural materials for gas turbine applications, due to their high strength‐to‐density ratio and excellent resistance to creep and oxidation . This alloy has been a topic of interest lately due to advancements of the β ‐stabilizing elements, such as Cr, Mn, and V in improving room‐temperature ductility and high temperature formability . Moreover, different kinds of fabrication routes were also adopted, such as powder metallurgy (PM), electron beam melting (EBM), hot isostatic pressing (HIP), and casting .…”
