Grain size gradient length scale in ballistic properties optimization of functionally graded nanocrystalline steel plates
Abstract
The last few years have highlighted the existence of two relevant length scales in the quest to ultrahigh-strength polycrystalline metals. Whereas the microstructural length scale - e.g. grain or twin size - has mainly be linked to the well-established Hall-Petch relationship, the sample length scale - e.g. nanopillar size - has also proven to be at least as relevant, especially in microscale structures. In this letter, a series of ballistic tests on functionally graded nanocrystalline plates are used as a basis for the justification of a "grain size gradient length scale" as an additional ballistic properties optimization parameter. © 2013 Acta Materialia Inc.
