Experimental investigation of forming limit, void coalescence and crystallographic textures of aluminum alloy 8011 sheet annealed at various temperatures

Aluminium and Its Interlinking Properties

“…The microstructure of the aluminium alloy containing silicon and iron consists of inter metallic phases which appeared as dark areas in the aluminium matrix as shown in Figure 2, and certain second-phase particles were found to be present in [30,[32][33][34][35]. Table 2.…”

“…An increase in the annealing temperature shows the presence of a larger amount of precipitated particles; the colour may be grey, which is due to the presence of silicon and white spots [25] is due to the presence of iron, which might ultimately increase the formability. The Fe and Si particles were capable of stabilizing a fine-grain/sub-grain structure, which could be used to develop interesting combinations of strength and ductility [2,[30][31][32][33][34][35]. Titanium increased the recrystallization temperature, induced grain refinement and remained mostly in solution [26].…”

“…The average strength coefficient (K) is comparatively less for the sheet Figure 2. Microstructure of aluminium alloy 1350 sheets annealing at four different temperatures [32,33]. Figure 3.…”

“…Ease of possessing light weight, formability and good strength-to-weight ratio are the desirable properties opted by the designer in the selection of materials for most modern engineering applications. Aluminium alloys vary by their tensile properties, formability properties and surface characteristics from one another at different dimensions, annealing temperatures, duration of annealing and mode of cooling, composition and percentage of initial strain [30][31][32][33][34][35]. In sheet metal forming, force is applied to a piece of sheet metal to modify its geometry rather then to remove any material.…”

Design and Application of a Quantitative Forecast Model for Determination of the Properties of Aluminum Alloys Used in Die Casting

“…This type of material wears better and exhibits a significant resistance to temperatures between 260 and 370 C. When tested at 315 C, it is three to four times more resistant than conventional aluminum alloys and can be produced at a price of half a dollar per kilogram. 11 In other studies, alloys 8011 34 and 3003, 13 usually manufactured in Venezuela for forming and rolling processes, are adjusted by the Ramberg-Osgood and Rasmussen equations, which initially consider factors such as nominal stress and strain. In addition, modulus of elasticity of the material and the test stress for the deformation, according to the offset method, 26 were considered to extend the equation and consider factors such as ultimate deformation and ultimate stress, which can be determined with 93% of elastoplastic behavior of the alloy, 8,37 ICME developed models based on the control of a particular property; within these, one of the most frequently analyzed properties is the hot crack, which occurs in the solidification process of the material once it has been injected into the permanent mold.…”
