The potential of ECAP processing of sheet material to refine the grain size, enhance mechanical properties, and improve deep drawability was determined for a
The present study concerns rolling of thin aluminum sheets where the grain microstructure becomes increasingly important as the sheet thickness is reduced. A sheet
Grain size and precipitations affect the strength and ductility of ultrafine-grained materials. In this study, aluminum alloy 6061 sheets were fabricated using the accumulative
The hardness differences in aluminum alloys resulting from grain refinement through twin-roll casting mcficantly impact their performance across various applications.
In this study, a cellular automaton–finite element (CA-FE) model was developed to predict the grain structure and texture of aluminum strips fabricated via TRC. Both pure Al and AA7075
Twin-roll casting (TRC) has emerged as a promising technique for producing aluminum alloy sheets with tailored microstructures and mechanical properties. The unique
In the present work, the application of the specialized ECAP equipment to refine the grain size in a representative aluminum sheet alloy (5005) is demonstrated, and the
In order to investigate the grain size effect on the tensile deformation behaviors, a series of model materials with uniform equiaxed grains, low dislocation density, high fraction

Polyron Industries Sdn Bhd has been supplying high quality materials for Sabah’s architectural, construction and advertising needs since 2005
Fig. 8 shows the histograms of the grain size of commercial pure aluminum sheets at different ARB cycles. The distribution of grain size after 2 ARB cycles is widespread,
Rolled products, i.e. sheet, plate and foil constitute almost 50 % of all aluminium alloys used (see Figure 1301.01.01). In North America the packaging industry consumes the majority of the
The structural and body parts highly rely on the formability of sheet metals [1], which is always characterized by the forming limit curve (FLC) [14], [15].The FLC defines the
A constitutive model is established, where microstructure parameters such as average grain size and dislocation density are allowed to evolve during plastic deformation of
Aluminum alloys are widely preferred because of their low density, castability, good mechanical properties and corrosion resistance in the automotive industry. Especially, A356 (AlSi7Mg0.3) alloy ...
Generally, the high strength results from a very high density of dislocations and grain boundaries that form during SPD. Typically, a steady state so-called ultra-fine grained
