Ti-6Al-4V alloy is a popular titanium alloy due to its high strength / density ratio, high toughness, superior corrosion resistance and good biocompatibility. After forming operations, Ti-6Al-4V is typically subjected to Solution Treatment and Over-Aging (STOA). Fatigue is one of the most frequent causes of failure in mechanical components. The prediction and optimization of the strength of structural components under cyclic loads therefore plays a strategic role and must take into consideration the presence of defects. The aim of the work is to investigate the axial fatigue behaviour of Ti-6Al-4V alloy not subjected to STOA in inert environment in the presence of notches. The experimental results agree well with the results obtained using the Haigh diagram.

Abstract

Ti-6Al-4V alloy is a popular titanium alloy due to its high strength / density ratio, high toughness, superior corrosion resistance and good biocompatibility. After forming operations, Ti-6Al-4V is typically subjected to Solution Treatment and Over-Aging (STOA). Fatigue is one of the most frequent causes of failure in mechanical components. The prediction and optimization of the strength of structural components under cyclic loads therefore plays a strategic role and must take into consideration the presence of defects. The aim of the work is to investigate the axial fatigue behaviour of Ti-6Al-4V alloy not subjected to STOA in inert environment in the presence of notches. The experimental results agree well with the results obtained using the Haigh diagram.
