摘 要：<正>Microstructures of a CuZnAlMnNi shape memory alloy in the as-quenched and long-term aged conditions wereinvestigated by transmission electron microscopy. Aged for one year in martensite phase, an equilibrium α-phase with fccstructure was observed in the M18R martensite matrix, accompanied by the appearance of a novel diffraction pattern. Byanalysis, it was suggested that the novel pattern results from the α-phase and the martensite matrix remaining in seven fineplates which produce intense secondary diffraction effect when the diffraction beams enter from one phase into another.
