“…In this case, the titanium waste reaches 45 -65% [5]. Ti-Al alloys are widely used in alloying and modifying aluminum and its alloys [6], in production of valves in automobile engines [7,8], as heat-resistant, corrosion-resistant and wear-resistant coatings [9,10], and as a filler material for arc welding [11], since titanium aluminides are easily crushed to a powdery state. Titanium aluminides are also used for the manufacture of catalysts [12], getters and Raschig rings for rectification columns [13], as a reducing agent in metallothermic processes in the preparation of ligatures for titanium alloys [2], as additives to carbon-graphite materials to improve the crystal structure and so on.…”
