“…However, the present data is on extruded and rolled alloys which do have a strong texture, and we will take account of that. For rolled and extruded alloys, generally the yield strength will be lowest in a direction at a 45° angle from the longitudinal (L) direction (see [62] for Al-ZnMg extrusions, [63] for Al-Cu based sheet, [64] for commercial purity sheet, [65] for a recovery annealed aluminium alloy), and the L direction has the highest yield strength. The increment in M in the L direction compared to the texture free case is on average 5% (from data in [50,61,63,64]).…”

An expanded model for the thermodynamics of co-clusters and their strengthening is presented, and the model is applied to predict co-cluster formation and strengthening in AlMg-Si alloys. The models are tested against data on a wide range of Al-Mg-Si alloys aged at room temperature. The strengthening due to co-clusters is predicted well. The formation of the co-clusters is studied in an Al-0.5at%Mg-1at%Si alloy using three-dimensional atom probe analysis. The results correspond well with the model. It is shown that in general, (shortrange) order strengthening due to co-clusters will be the main strengthening mechanism in these alloys. Apart from the co-clusters, Si clusters also form, but due to their low enthalpy of formation, they contribute little to the strength.
