Abstract
This paper deals with results obtained in fatigue crack propagation at 500 degrees C in Ti6242 and Ti6246 alloys. Following an analysis of the influen ce of alloy composition and microstructure, the influence of the gaseous at mosphere is specially studied on the Ti6246 alloy. A corrosion fatigue mech anism is shown to be related to an embrittling effect of water vapour. An a dditional stress corrosion cracking mechanism is operative for some critica l conditions.
