A large number of mechanisms limit the ductility of engineering materials, ranging from necking to ductile fracture. Two quintessential examples are addressed in this talk. First, heterogeneities and strain localizations dominate in metallic glasses, which lead to interesting dependence of ductility on structural/thermomechanical inhomogeneities and geometric features such as notches. Second, high entropy alloys allow an unprecedented freedom in alloy design, from which various strengthening mechanism can be superposed and improve the overall mechanical properties. An example will be given on NiCoCr-3W alloys.
