Abstract

Abstract : Nanocrystalline Alloys In article number 2200354, Jason Trelewicz and co‐workers connect nanocrystalline stability regimes with temperature‐dependent segregation states through in situ mapping of microstructural evolution in Mo–Au nanometallic multilayers combined with thermodynamic predictions of stable solute configurations. These findings provide a framework for decoupling thermodynamic and kinetic contributions to the stability of nanocrystalline alloys exhibiting a transition from grain‐boundary segregation to solute clustering and nanophase separation at elevated temperatures.
