Effect of Ultrasonic shot Peening on microstructure corrosion and low cycle fatigue behavior of the alloy Ti 6Al 4V

Abstract

Ti–6Al–4V alloy is used for wide applications such as chemical and aerospace industries due to high specific strength. It is also used in orthopaedic and dental bio-implants because of their excellent biocompatibility and corrosion resistance in physiological environments due to formation of protective oxide layer of TiO2. It has dual phase microstructure with primary α and transformed β. The Al is support to α phase however; V is β phase stabilizer element at room temperature.
