Abstract:In this study, Cu/Al/Ag layered composites with two silver powder concentrations (2 and 3 wt.%) were fabricated with the aid of accumulative roll bonding (ARB). The ARB‐ed samples were heat treated at different temperatures (750, 850, 950 and 1050 °C), times (30, 45 and 60 minutes) and cycles (1‐9 cycles) to produce Cu‐Al‐Ag shape memory alloys (SMAs). The samples were characterized by X‐ray diffraction (XRD), scanning electron microscope (SEM) and electron backscattering diffraction (EBSD). Phase transformati… Show more
