A team of researchers from the University of Vermont, Lawrence Livermore National Laboratory, Ames Laboratory, Los Alamos National Laboratory, and UCLA (Prof. Jaime Marian) have made the strongest silver alloy ever, 42% stronger than the previous world record, while not losing electrical conductivity. This was achieved by using a combination of selective Cu alloying in trace amounts and an ultrafine nanotwinned microstructure to delay the onset of softening typically seen in nanocrystalline metals. The team’s results were published on September 23 in the journal Nature Materials.
