Experimental validation of microstructure evolution in crystalline materials

Abstract

The influence of initial grain orientation and geometrical restrictions (grain boundaries, sample geometry) on the microstructural evolution was investigated at ambient temperature. Single- and polycrystalline austenitic steel samples, strained under uniaxial tension, show pronounced orientation changes which are strongly dependent on initial orientation. The numerical simulation results from a crystal plasticity FEM model match the experimental ones. © 2010 IOP Publishing Ltd.
