| Abstract Scope |
Ultrafine-grained materials have gained interest in recent years due to their unique properties when compared to their coarse-grained counterparts. In this work, microstructural refinement to the nanoscale and grain size stabilization in dilute binary Ag alloys is achieved through mechanical alloying (MA) followed by consolidation with spark plasma sintering (SPS). The mechanical properties of this alloy are probed with micro-tensile testing and micro-indentation. The microstructure is examined with electron microscopy revealing the presence of nano-scale grains and dispersoids, significantly bolstering the strength of the material as compared to that of pure unalloyed silver. The results forecast the ability to process high-strength, high-conductivity Ag alloys for electronic and structural applications. |
