TL;DR: It is shown that a simple VCoNi equiatomic medium-entropy alloy exhibits a near 1 GPa yield strength and good ductility, outperforming conventional solid-solution alloys, demonstrating that severe lattice distortion is a key property for identifying extra-strong materials for structural engineering applications.

TL;DR: In this article, the effects of prior austenite (γ) grain boundaries and microstructural morphology on the impact toughness of an annealed Fe-7Mn-0.5Si medium Mn steel were investigated for two different microstructure states.

TL;DR: In this article, the authors investigated the sequence of precipitation on grain boundaries in comparison to the bulk in a model Al-Zn-Mg-Cu alloy and quantified the difference in kinetics between grain boundary and bulk precipitation.

TL;DR: In this article, a near-atomic-scale approach was used to investigate the details of the compositional decoration of grain boundaries in the coarse-grained, columnar microstructure in parts built from a non-weldable nickel-based superalloy by selective electron-beam melting.

TL;DR: In this article, the deformation and strain hardening mechanisms of Mn-containing steels that utilize complex dislocation substructures, nanoscale precipitation patterns, deformation-driven transformation, and twinning effects are discussed.
