Influence of Equal Channel Angular Pressing Technique on Mechanical Properties, Corrosion Resistance, and Microstructural Behavior of Al-Alloy 5083
During severe plastic deformation (SPD) processing, aluminum alloys exhibit
moderate strength and ductility. Nevertheless, the materials' ductility, as determined by tensile
testing, does not accurately represent their capacity for plastic deformation. After the tensile test, its
material, aluminum alloy 5083, was observed to be super ductile.
The results of a more thorough plasticity analysis—applied for the first time to material
following SPD processing—are presented in this paper. The aluminum alloy 5083 is examined in
the patent both before and after equal channel angular pressing (ECAP). A highly effective aluminum
alloy 5083 specimen preparation was suggested. Under heated temperatures, the process involves
severe plastic deformation. Optical microscopy and scanning electron microscopy (SEM)
were used for micro-structural research in order to look at the distribution of second-phase particles
and the evolution of grain structure. Furthermore, Vickers micro-hardness testing was utilized to assess
the mechanical characteristics of the alloy after processing. The outcomes showed that after
ECAP processing, there was a significant decrease in grain size and an increase in micro-hardness.
Additionally, the production of a finer microstructure with a more uniform distribution of
strengthening precipitates was clarified by electron microscopy (SEM). The micro-structural evolution
and mechanical behavior of aluminum alloy 5083 under ECAP are well-explained in this patent,
which may lead to improved performance in structural applications. This method can be used
to forecast fractures in plastic deformation processes and estimate the final plasticity of the materials
for various stress-strain states after ECAP processing, as well as the mechanical properties discussed.
Due to its unique mechanical qualities, aluminum alloy 5083 shows great potential in a
variety of structural applications. The effects of Equal Channel Angular Pressing (ECAP) on the
hardness and microstructure of aluminum alloy 5083 were examined in this patent work.
The specimen's mechanical characteristics are at their finest following a single deformation when the temperature reaches 300°C. Compared to the original specimen, the tensile strength observed enhanced after the fourth pass, and breaking elongation (28.3%) was improved. Through second-phase strengthening and fine-tuning, the recrystallized grains and second-phase particles increase the material's strength.
