The well known peaks at -40℃ and 160℃ are caused by twin boundaryrelaxation and martensitic transformation respectively. The new peak at 40℃is associated with the martensitic phase transformation in the poor Mn region, whichwas frmed by spinodal decomposition. The relaxation peak at 200℃ is attributed toα-Mn precipitate. The activation energy of the peak is 1.1 eV. The relaxation peakat 340℃ occurred only after aging under vacuum at 430℃. The peak height increas-ed through aging. The activation energy is 1.47 eV. The peak is supposed to relateto spinodal decomposition in which the Cu-rich region formed.
