INFLUENCE OF MICROSTRUCTURE ON BETA-CEZ T ITANIUM-ALLOY CREEP-BEHAVIOR

This article completes a study concerning the analysis of ''microstruc ture - creep behaviour'', relations of the titanium beta-Cez alloy in the range of intermediate temperatures. It concerns notably the influe nce of the morphology of the intragranular primary alpha phase (alpha( p)) on the parameters characterizing primary creep. It is shown that t hese parameters are paired and depend on the surface (in 2D) of the pa rticles of the alpha(p) phase. The role of the beta ex-joints is also mentioned.
