Abstract Scope |
In this work, microstructural refinement to the ultrafine-grained scale and grain stabilization in dilute Ag
alloys is achieved through two separate processing methods: by a combination of mechanical alloying
(MA) and spark plasma sintering (SPS), and by high pressure torsion (HPT). The mechanical properties
are probed through micro-indentation and micro-scale mechanical testing, and the microstructure is
examined with electron microscopy revealing the presence of multiple strengthening mechanisms,
significantly bolstering the strength of the material as compared to that of pure unalloyed and
unprocessed silver. The results forecast the ability to process high-strength, high conductivity Ag alloys
for electronic and structural applications. |
