“…From the equilibrium phase diagram, three different kinds of particles may be present in this alloy, namely, fine ␤ precipitates (Al 3 Mg 2 ), [22,23] large constituent particles such as Al 6 (Mn,Fe) and Mg 2 Si, and submicron size Al 6 (Mn,Fe) and MnAl 6 dispersoids. Of these, the ␤ precipitates will be excluded from any further discussion, because they require an extensive low-temperature aging process to form.…”

The relative importance of shear banding, particles, and grain size in determining the rolling and recrystallization textures of a twin-belt strip cast AA5754 aluminum alloy has been investigated. Various thermomechanical processing schedules have been employed that incorporate homogenization, warm and cold rolling, and intermediate anneals in various combinations prior to a final recrystallization treatment. Despite its inherent susceptibility, the alloy undergoes limited shear banding during rolling and displays a large random component of the deformation texture. The effect is most pronounced in the as-cast alloy subjected to cold rolling without any prior or intermediate heat treatments. This can be attributed to the denser distribution of particles, a greater scattering of the initial texture, and a relatively small grain size. Homogenizing prior to cold rolling promotes more extensive shear banding and accelerates the development of a strong rolling texture. A grain shape effect results in a prominent S component in the rolling texture at higher reductions, irrespective of the processing history of the material. In the heavily rolled as-cast alloy, the recrystallization texture is dominated by Cube and R components indicating the prevalence of oriented growth processes. However, homogenizing the as-cast alloy prior to cold rolling imparts a characteristic recrystallization texture with strong CH component, which is most likely due to selected growth of grains following particle-stimulated nucleation.

Age hardening response was investigated in Aluminum 6061 alloy to determine the influence of trace additions of 0.01 and 0.1 % of cadmium, 0.01, 0.1 and 0.5% of silver, 0.05 and 0.1% of zirconium, as well as 0.1% each of Cd + Zr and Ag + Zr. Thermo-mechanical stabilization treatment followed by artificial aging of these alloys were carried out at 313 K, 353 K, 393 K and 453 K. Vickers hardness was used to monitor the progress of age hardening. The Precipitate morphology, distribution and size were studied by Scanning Electron Microscopy. Tensile tests on selected alloys after selected treatment conditions assisted in determining the UTS, YS and % elongation. Fractography of the tensile fractures by scanning electron microscopy was used to delineate the effect of trace element addition on the fracture type. The trace addition effects observed seem to be caused by the precipitate size refinement and distribution. The observed effects seem to corroborate results obtained by several other techniques. The present work strengthens, both qualitatively and quantitatively, the viewpoint that it is possible to choose an age hardenable aluminum base alloy and improve it significantly by making judicious additions of trace elements.
