The different length scales entering the modelling of mechanical properties of metals are reviewed in order to address open questions concerning the relation between microstuctural scales and macroscopic properties. The relative importance of structural hardening and composite hardening, the role of dislocation microstructures are given as examples of cases where only part of the available information on the structure is relevant. The structural hardening by a bimodal distribution of precipitates and mechanical properties of foams are given as example of the importance of dispersions of scales compared to their average values. The form of performance indices for corrosion related problems exemplifies the relation between scale and time in materials selection problems.
