Titanium alloys are widely used in various aerospace, marine, chemical industries, medical, and military applications because these alloys have high specific strength, high Young’s modulus, and excellent corrosion resistance.
Due to their excellent complex of physical, chemical, and mechanical properties, titanium alloys are unique materials for many branches of industry. An important feature of titanium is its high reactivity concerning the interstitial chemical elements (oxygen, nitrogen, and carbon). The absorption of interstitial elements by titanium alloys causes change in physical and mechanical properties of alloys and articles which are made of them. It should be noted that the titanium alloys are classified, in particular, by the compositions of their structures.
