Abstract

The tensile and fatigue testing results of Staley Jr. et al. [Mater. Sci. Eng. A 460–461 (2007) 324 and Mater. Sci. Eng. A 465 (2007) 136] for A206-T71 castings were reanalyzed. The Weibull distributions for both elongation and fatigue life of castings that were hot isostatically pressed (HIPed) as well as those that received no processing (no-HIP) were correlated. Results indicate that significant improvements in fatigue performance are possible if pores and old oxides are eliminated. Extrapolations of results and underlying mechanisms are also discussed.
