PRELIMINARY STUDY OF ORDER-DISORDER REACTION IN A Ni3 Fe0.76Al0.24 ALLOY BY MEANS OF ATOM-PROBE TECHNIQUES

D. Blavette , S. Chambreland

Atom study of ordering in a Ni3 Fe0.76 Al0.24 has been undertaken. Analyses of the (001) superstructure planes of the one phase alloy exhibit the alternation of mixed planes (50 % Ni, 50 % Al, Fe) with pure planes (100 % Ni). A rupture of this stacking sequence was observed and has been correlated to the occurence of an antiphase boundary between ordered domains. Composition of phases existing at higher temperatures has been determined in spite of the weak difference between matrix and precipitate composition and the small particle size.
