Exploring the limits of metal strength
Where: virtual on Zoom (link follows)

We studied the uniaxial compression behavior of micro- and nanoparticles of several elemental metals (Au, Ni, Ag, Mo, Pt) and alloys (Ni-Fe, Ni-Co, Au-Ag). The particles were obtained by solid state dewetting of thin metal films and multilayers deposited on sapphire substrates. The record-breaking compression strength of the particles (i.e. 46 GPa for Mo) and counterintuitive solid solution weakening are discussed in terms of nucleation-controlled dislocation plasticity.
