- Abstract
Heterogenous bimodal harmonic-structure (HS) materials are interesting because of excellent structural efficiency. In this work, we present a simple yet powerful analytical model allowing to evaluate strain partitioning between coarse- and ultrafine- grain (CG and UFG, respectively) structure components in HS materials and to estimate the magnitude of back-stress forming at their interphases. The analysis of experimental results on pure nickel using this model shows that HS promotes a favourable strain partitioning between CG and UFG components and the build-up of back-stress in the vicinity of their interfaces allowing the material performance to exceed expectations from the rule of mixtures.
