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.
期刊介绍：
Scripta Materialia is a LETTERS journal of Acta Materialia, providing a forum for the rapid publication of short communications on the relationship between the structure and the properties of inorganic materials. The emphasis is on originality rather than incremental research. Short reports on the development of materials with novel or substantially improved properties are also welcomed. Emphasis is on either the functional or mechanical behavior of metals, ceramics and semiconductors at all length scales.
