Twinnability of bimetal interfaces in nanostructured composites

Abstract

Bimetal interfaces hold the extraordinary potential to promote or suppress deformation twinning in nanostructured composites. This article constructs a methodology for developing maps for identifying the twinnability of chemically sharp, bimetal interfaces based on their structure and properties. The map is shown capable of rationalizing the variation in experimental observations among several different bimetal interface structures. © 2013 I.J. Beyerlein, J. Wang, K. Kang, S.J. Zheng, N.A.
