Abstract
Ti-6Al-4V was used to study some fundamental aspects of fatigue. Although, a variety of microstructures and surface conditions were compared, the majority of work was performed on smooth specimens in the beta annealed condition. Additional tests were made on specimens coated partially with spherical titanium particles and on standard FM specimens. An extensive SEM survey of surfaces was performed to elucidate the characteristics and growth behaviour of small surface cracks (microcracks and short cracks). Concepts of crack arrest and of an apparent fatigue limit were advanced. A comparison between individual segments of macrocracks and short cracks was proposed; mechanisms responsible for fatigue crack behaviour were tentatively deduced.
