Nanomechanical testing of bcc micropillars – power laws and lattice resistance correlations
September 29-October 4, 2019
It is now well established that the compression plastic flow stress, sp, of metallic micropillars increases with decreasing sample diameter. With fcc metals, if the pillar flow stress and pillar diameter are normalised by the shear modulus resolved onto the active slip system, m, and Burgers’ vector, b, respectively, the data follows an empirical relation of
