%X The changes of atomic order state during aging of the parent phase and martensite in an as-quenched Cu-Al-Ni-Mn-Ti shape memory alloy were investigated by X-ray diffraction and in situ electrical resistivity measurements. It was shown that the aging mechanisms of the parent phase and martensite are different. During parent phase aging, DO_3 atomic reordering occurs, leading to an increase in the degree of long range order. During martensite aging, however, short range atomic disordering takes place, resulting in the stabilization of martensite.
