Abstract
A creep-brittle titanium alloy Ti-6242, which is being used for aeroengine applications, was chosen to study the effects of loading conditions and microstructure on creep crack growth (CCG) behaviour at 500°C. Tests were made on compact tension (CT) specimens under both displacement rate control and under constant load. Crack growth data were correlated with C* (t), Ct and the J−integral. The validity range of correlation of the various crack-tip parameters for a growing crack in creep-brittle materials is discussed.Keywords
