AbstractTitanium has low density (4.5 g / cm³), high specific strength, fracture toughness, fatigue strength, resistance to crack propagation, high toughness at low temperature and excellent corrosion resistance [1]. Pure Titanium is anti-toxic, anti-allergic and completely biocompatible [2]. Titanium has an allotropic structure [3]. Aluminum, tin, gallium and zirconium elements known as alpha stabilizers exhibit good properties at high temperatures. The elements of vanadium, molybdenum, niobium, tantalum, chromium which decrease phase transformation temperature are known as β stabilizer. When β-stabilizing elements were examined, they were usually found in brittle structures [4]. The creep resistance of α alloys is better than β alloys and α alloys are used for high temperature applications. β alloys can be heat treated and can not be applied to α alloys. The α + β alloys consist of a mixture of α and β phases, and these alloys have a good formability properties [5].
