**Electron Structure:** The Group 5 elements are nearing the middle of the transition elements. Group 5 elements have five bonding electrons each due to hybridization (see below), and they are higher melting than the Group 4 elements (Ti, Zr and Hf). This logically follows the idea that the more bonding electrons an element has, the stronger its bonding will be, and therefore the higher the melting temperature. V, Nb and Ta have electron structures of: *(inert gas core) + d^3 + s^2* which hybr... Phase diagrams of Ti-Al system. done using FactSage Thermo-chemical Software and Database [19].

Al alloys changes from α-Ti (α) to γ-TiAl (γ) and the microstructures of solidified alloys evolve from spherical primary dendrites and matrix phases to cellular dendrite phases. Meanwhile, for the Ti-(47, 50) at.% Al, the transformation temperature of metastable intermediate α phase decreases with the increase of undercooling.

Ti-Al binary phase diagram (BPD) is the most important phase diagram of Ti alloys. Aluminium is as essential for alloying titanium as carbon is for iron. Aluminium is the most abundant metal in the earth's crust (8.8 %), and it has found large applications due to its low density (2.71 g/cm3) and high corrosion
