“…The results indicate that the volume-weighted average grain size, based on the rule of mixtures, captures the response of the material better than the average grain size as the characteristic length of the microstructure. This finding is supported by earlier investigations, where the rule of mixtures has been successfully applied to model grain boundary behaviour [50], elastic properties of multi-phase materials [51], and strength of composites [52,53].…”

The strength of polycrystalline metals increases with a decrease in grain size according to the HallPetch relationship. However, heterogeneous microstructures deviate from this relationship depending on the distribution of grain sizes. This paper introduces a rule of mixtures based approach for determining the characteristic length of the microstructure for heterogeneous weld metal. The proposed grain size parameter, the volume-weighted average grain size, is measured experimentally for nine structural steel weld metals and two base materials. The weld metals are found to have a large variety of grain size distributions that are noticeably broader than those of the base material due to differences in phase contents. The results show that the volume-weighted average grain size is able to capture the influence of grain size distribution on the strength of welded structural steel. Based on the experimental results, a modified Hall-Petch relationship is formulated for the strength prediction of heterogeneous microstructures. The modified relationship is also found to be applicable to data from the literature.
