Abstract

The paper reviews a number of factors which influence the crack tolerance of titanium alloys, particularly those which are generally encountered in the application of titanium alloys to aerospace hardware. Among these factors are cryogenic temperatures, heat treatment, interstitial element content, elevated temperature exposure, cold working, and aggressive environments. In addition a discussion of plane strain fracture toughness data for titanium alloys is given.
