Abstract :
[en] Transition phases occurring during isothermal aging at 250°C af ternary Zri-A1-Cu alloys are modlifîed after creep at high temperature. fle pressure applkd during creep leads to a high dertsity of clef ects which modifies the ndcrostructure. 11e trnsitiôn phases are studied by me ans of transmission electron microscopy and diffraction technique. Œ’r and phases pile up on dislocations. 11e reaction «s + £ 4 T +r 1$ accelerated and the transition T’ -. e’ is proxnoted by the defects.
