摘要：

An unusual fatigue behavior, observed in the alpha+beta microstructures of the beta-titanium alloy, Ti-10V-2Fe-3Al, is reported. It is the duality of the S-N fatigue curve where the fatigue data of specimens failing from cracks nucleated at the surface and subsurface regions grouped in to two separate S-N curves. The microstructural factors causing this effect are analyzed. (C) 2003 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
