“…Improving the twin-roll cast strip quality and optimizing its subsequent processing are of great importance for the production of high quality aluminum foil [5][6][7]. During the process of producing aluminum foil, heat treatment is an effective method to obtain the predicted performance by refining grain size of twin-roll cast strip [8].…”

AA8021 aluminum alloy twin-roll cast strips with 7mm gauge were rolled to 3.8mm gauge sheets and given homogenization, further rolled into 0.55mm gauge foil stocks with intermediate annealing. This paper investigated the influence of homogenization conditions on microstructures of foil stocks in detail. The results show that, for the foil stock made from the sheet without homogenization, the grain structure is partially recrystallized. While the grain structure of foil stock made from the sheet with medium temperature homogenization is fully recrystallized, but it is coarse near sheet surface. However, foil stock made from the sheet with high temperature homogenization has fine and uniform recrystallized grain structures. The differences of grain structures among these three kinds of foil stocks can be understood by the variation in solid solution content of Fe, Si, Mn and distribution of intermetallic compounds. The optimized homogenization condition was adopted by our plant to produce foil stock, and its grain structure was fine and uniform. The surface quality of final aluminum foil rolled from the foil stock could meet high grade requirements of customers.

“…Mark Easton et al has derived a relation between grain size (d) and solute content , considering a growth restriction factor Q, potency and number density of nucleant particles, The term a is related to the maximum density of active TiB2 nucleant particles within the melt, while b is related to their potency[23]. [23][28]. W. Schneider (Sp) et.al has detailed in his review on the importance of particle size of inoculants to achieve grain refinement, like AlTiB grain refiners should have a particle size of 3 to 4 μm[28].…”

In the past few decades Aluminium alloys have been extensively used in most of the structural applications, where there is a need to reduce weight and substantially providing structural strength and stability to the assembly. Aluminium alloys or Titanium alloys are the best possible options for the design engineers to select over alloy steel for structural applications when mass reduction is an important factor, However Aluminium alloys wins the race over Titanium alloys when cost is an important criteria for selection of materials. Aluminium alloys are chosen as an alternative next to titanium alloys when it comes to high strength to weight ratio. Titanium alloys particularly Ti6Al4V is selected for applications where the component is loaded with high temperature. Therefore engineers have to evaluate the loading conditions and its environment based on the properties of alloys for selection of Aluminium alloys over other alloys for structural applications. Material selection for the structural applications in various industries such as aerospace, automotive, Industrial and construction sector are based on its function, which depends on the factors like the loading conditions, environment, and functional requirements. The main strength requirements for structural applications are its mechanical properties namely Tensile strength either compressive or tensile load, The present review is to study and understand the characteristics of Aluminium alloys and ways to enhance the mechanical properties of Aluminium alloys.
