Among the titanium alloys, Ti-6Al-4V is the most widely used. In the present work, the uniaxial hot compressive behavior of Ti-6Al-4V has been investigated under constant strain rates. A series of dilatometery experiments were carried out to determine the transformation temperatures at different cooling rates. Specimens were homogenized at 1050 °C for 10 minutes followed by fast cooling to dif...

most of the materials used in the industry of aero-engine components generally consist of titaniumalloys. advanced materials, because of their excellent combination of high specific strength, lightweight and general corrosion resistance. in fact, chemical wear resistance of aero-engine alloyprovides a serious challenge for cutting tool material during the machining process. the reductionin cutt...

5 Abstract-Fretting fatigue is an important concern in the structures and machine parts that are subjected to repeated relative movements between them. In current study a review of the work done by various researchers related to the evaluation of fretting fatigue response of Ti-6Al-4V has been presented. Effects of surface treatments, crack growth, heat treatments, types of loading, contact pad...

Due to recent concern about allergic and toxic effects of Ni ions released from TiNi alloy into human body, much attention has been focused on the development of new Ni-free, metastable beta-type biomedical titanium alloys with a reversible phase transformation between the beta phase and the alpha'' martensite. This study investigates the effect of the stress-induced alpha'' martensite on the m...

Additive manufacturing (AM) of metals offers new possibilities for the production of complex structures. Up to now, investigations on the mechanical response of AM metallic parts show a significant spread and unexpected failures cannot be excluded. In this work, we focus on the detection of fatigue cracks through the integration of a Structural Health Monitoring (SHM) system in Ti-6Al-4V specim...

Titanium and nickel alloys represent a significant metal portion of the aircraft structural and en components and the residual stresses induced by machining are very critical due to safety sustainability concerns. This paper presents experimental investigations and finite element simulat on turning of Ti–6Al–4V titanium alloy and IN100 nickel based alloy with uncoated and TiAlN co tools. Face t...
