Abstract
Deep-rolling with subsequent annealing was performed on solution heat treated Ti-3Al-8V-6Cr-4Zr-4Mo to develop microstructural gradients in the notch root. Annealing treatments were varied to a wide extent to e valuate optimum conditions for excellent fatigue performance and outst anding fracture toughness of a component. Such a property combination cannot be achieved by non-gradient microstructures. (C) 1998 Elsevier Science S.A. All rights reserved.
