摘要: Friction stir processing of a ternary immiscible alloy was investigated as pathway to thermally stable nanostructured alloys. The processed characterized using x-ray diffraction (XRD), scanning electron microscopy (SEM), nano-indentation, and thermal stability analysis. Both XRD high-magnification SEM confirmed the formation solid solution at shear edge friction layer. Microstructural inhomogeneity observed in region that resulted hardness variation. Upon annealing treatment, significant improvement 200°C due nano-precipitates. Remarkably, Cu-Ag-Nb system displayed exceptional up 500°C.
