Evolution of interfacial character and its influence on strain hardening in dual-phase high entropy alloys at nanoscale

Heterogeneous phase interface with particular microstructure generally plays a key role in the mechanical behavior of nanostructured metals and alloys. Here, we reported a novel high-entropy phase interface with extraordinary property that is strongly dependent on the lattice mismatch and length scale in dual-phase high entropy alloys (DP-HEAs) multilayers. A disorder intermediate layer, fcc-to-amorphous and bcc-to amorphous transition...
