Fatigue in Ti-6Al-4V at Very High Cycles
Materials Science Forum, 2007The importance of determining and understanding the very high cycle fatigue behaviors of materials has gained strength in recent years. Ti-alloys, in view of their high strength-to-weight ratio, have a range of structural applications. Of these, Ti-6Al-4V, belonging to the alpha-beta type is the most widely used.

Very High Cycle Fatigue Behaviour under Cyclic Torsion Loading
2008Several technical components are stressed in cyclic torsion. Valve springs, for example or torque transmission shafts must withstand high numbers of torsion load cycles in service, and fatigue properties of materials under these loading conditions are of great interest therefore.

Very High Cycle Fatigue and Damage Behavior of Ti6Al4V
Key Engineering Materials, 2015High frequency fatigue tests were carried out with a 20 kHz ultrasonic testing facility to investigate the cyclic deformation behavior of Ti6Al4V in the Very High Cycle Fatigue (VHCF) regime in detail. The S,Nf -curve at the stress ratio R = -1 shows a significant decrease of the stress amplitude and a change from surface to subsurface failures in the ...

Very High Cycle Fatigue Behavior of High Strength Steels
2008Life extension of engineering plants and high-speed operation of engineering machines are required in various fields. In these situations, conventional fatigue strength determined as the strength for 107 cycles is not sufficient. It is necessary to adopt the data up to giga cycle regime for design and maintenance.

Adhesives in Very High Cycle Fatigue testing
2016The versatility of adhesive bonding creates new opportunities also for the experimental activities. One example is Very High Cycle Fatigue (lives up to 1E+10 cycles) [1] testing, in which the axial vibration generated by a piezoelectric transducer in the range of kHz is applied to the specimen by means of a horn-shaped adapter, which increases the ...

Very high cycle fatigue of additive manufacturing metals
The research on the Very High Cycle Fatigue (VHCF) response of materials has gained increasing attention in the last few years. Indeed, the fatigue life of components has significantly increased and can exceed one billion of cycles in many industrial sectors, such as, automotive and aerospace sectors.Caivano, Riccardo +3 more

An understanding of very high cycle fatigue of metals
International Journal of Fatigue, 2003Abstract For modern technical applications like cars, trains, and aircrafts, the durability of some components is between 108 and 1010 cycles. However, there are very few experimental results beyond 107 cycles, where the standard fatigue limit is predicted using statistical approaches.
