Abstract

It has been observed that formation of nanoscale interfacial disordered layers adjacent to grain boundaries of highly ordered grains leads to ultrahigh yield strength accompanied by large tensile ductility of the alloy. We propose a theoretical description and formulate criteria of existence of such layers and present strategies of alloy design based on the proposed theory.
