    Cyclic deformation behavior of high-purity titanium single crystals: Part I. Orientation dependence of stress-strain response

    Randomly oriented single crystals of high-purity titanium were prepared by strain annealing and were subjected to multiple-step fatigue testing under strain-controlled conditions, in order to determine their c...

    The dislocation and martensite substructures of a fatigued, polycrystalline, pseudoelastic Cu-AI-Ni alloy

    Polycrystalline Cu-AI-Ni specimens, subjected to pulsating compression fatigue, while capable of pseudo-elastic deformation, nevertheless exhibit cyclic hardening and fatigue fracture, as reported inMet. Trans. A

    The cyclic stress-strain response of polycrystalline, pseudoelastic Cu-14.5 wt pct Al-3 wt pct Ni alloy

    Limited results on the fatigue of pseudo-elastic material indicate that, as a class, these materials should have truly outstanding fatigue properties. To check this, the mechanisms of cyclic deformation and fr...
