“…In other rolling mills, a two-stage homogenisation practice is applied, where the slabs are heated to a soaking temperature of 600 °C, held for a few hours, then cooled down to a sub-homogenisation temperature of 500 °C and held again for a few hours to achieve a uniform temperature throughout the slab before being transferred to the hot rolling line (e.g. [15,17,21,25]). In the present study, samples for microchemistry analysis in the homogenised state were either taken from the homogenised slabs as described beforehand for the as-cast material.…”

“…The ratio of α-Al(Fe,Mn)Si to Al 6 (Mn,Fe) constituents found in the different alloys was matched very well in the Alstruc simulations. The ratio of the two phases was mainly driven by the Si content in the alloys, in that increasing Si concentrations favoured α-Al(Fe,Mn)Si to the detriment of Al 6 (Mn,Fe) [15,16]. Additions of Cu were either dissolved in the (Al)-matrix or co-precipitated in the main constituent phases, namely Al 6 (Mn,Fe) and α-Al(Fe,Mn)Si.…”

“…[11][12][13]). It is noted that during the production of Al beverage cans, a certain fraction of the -harder -α-Al(Fe,Mn)Si phase is desired to reduce the pick-up of Al at the ironing tools and hence improve the materials galling resistance [3,[14][15][16][17]. Moreover, homogenisation of AA 3xxx alloys is accompanied by the formation of a second fraction of much smaller, finely dispersed particles, which usually are called dispersoids.…”

An important aspect of the characterisation of non-heat-treatable Al alloys is the constitution of the material in terms of its alloying elements in solid solution and, in turn, volume, size, morphology and species of second-phase particles. These constitutional characteristics, conveniently summarised as micro-chemistry, have an impact on physical and mechanical materials properties of Al semi-finished products. In the present study, the evolution of micro-chemistry in the Al–Mn alloys of the AA 3xxx series during solidification and homogenisation is analysed. Especially, we focus on the impact of additional alloy elements, including Si, Mg and Cu, on the phase selection during solidification and the changes in solute level and volume, size and type of second-phase particles during subsequent homogenisation.

“…1978) is a popular method of simulating rolling, given the similarity of the strain path of the technique and the centreline of a rolled strip. This similarity prompted Alcan International Ltd to develop the technique (Bolingbroke et al . 1993) to allow the entire simulation of the strains, strain rates and thermal histories associated with multi-stand rolling, with a view to using the simulation process to simulate the development of both deformation and annealing textures in hot-rolled and annealed aluminium.…”

Aluminium is a readily deformable metal and, even when alloyed to achieve acceptable engineering mechanical properties, retains sufficient malleability to allow deformation processing, hot and cold, into thin or complex shapes by rolling, extrusion or forging. The world now takes for granted aluminium foil, thin section extrusions and aerospace forgings, each of which was a marvel in its day, and each of which has required much empirical work to define the process route to achieve acceptable mechanical properties and, hence, it is assumed, microstructure. Indeed, the very complexity of many shapes in aluminium has largely hindered the use of any simulation technique to help optimize these products, including modelling, until very recently. Even now, the tortuous strain path followed, for example, by a volume element undergoing extrusion through a port-hole die even defies analysis, let alone simulation, and empiricism must reign.For the more simple geometries of rolling and, to some extent, forging, these more clearly constrained strain paths allow closer analysis, simulation and, albeit at the early stages, modelling, of the development of microstructure and properties in the cold-rolled or hot-rolled state. This paper considers the needs of the aluminium industry, as defined by the end-product (customer) requirements. Predicting the development of the deformed state, in terms of the driving force for subsequent recrystallization and microstructure and crystallographic texture development during deformation, will be considered, together with the subsequent control of annealed structure and properties, including crystallographic texture. Consideration will also be given to the on-line measurement of microstructure and properties with implication for online control during manufacture. It will be shown that a combined approach using physical, as well as numerical, models, allows for the successful development of new products and the supporting scientific discipline.
