The fundamental processes driving plastic recovery following high strain rate loading of a metallic multilayered system based on the AgCu eutectic is explored using a combination of in-situ straining experiments in the transmission electron microscope, characterization of the deformed microstructure following loading at 10<sup>3</sup> s<sup>-1</sup> and molecular dynamics computer simulation. It will be shown that plastic recovery is dependent on the interface type, cube-on-cube or incoherent twin; loading direction with respect to the interface normal; total plastic strain; and thickness of the Ag-Cu bilayer. This plastic recovery will be shown to be driven by dislocation processes as well as interface restructuring and rearrangement. The decrease in degree of recovery with increasing plastic strain is accounted for by the complexity of the dislocation structures within the layers.
