Alternative length scales for polycrystalline materials-II. cluster morphology
Abstract
In a preceding paper we have proposed that a physically relevant length scale for polycrystalline materials is that associated with clusters of grains sharing special boundaries. Here we examine how that length scale changes with microstructure evolution under various external influences. We also discuss how the length scale may be reflected in constitutive relations for several examples of physical and mechanical properties of polycrystalline materials. © 1991.
