The domains of highly ordered phase andthe transition regions at grain boundaries appear, the twin boundaries damage. Furthermore,the microstructure also gives the appearance and growth of antiphase domains like rectangularnetwork. The long period antiphase structures and the antiphase domains have been cbserved atthe single diffracted vector g. The concentration gradient of Al has been found from the ma-trix to the grain boundaries, the matrix is poor in Al and the grain boundaries are rich in Al.
