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 current study 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. Equal channel angular pressing process under Severe plastic deformation. The findings indicate that the optimal grain refining effect following secondary deformation occurs at 300°C, with an average grain size reduction from 50μmto 10μm. 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. 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

When the surrounding air temperature falls below the freezing point of the water, ice commonly forms inside steel pipes, airplane wings or on wind turbine blades. The internal pressure of frozen pipes causes them to bulge and burst, which can result in significant property and equipment damage as well as significant financial losses. The ice formation on the airplane wings or can poses serious challenge to the security of passengers. On wind turbine blades ice formation can lead to low efficiency of the system. Therefore, it is necessary to design a very effective deicing/ant icing system to reduce the negative effects of freezing. The objective of this review is to explore the effectiveness of different heating systems in heating and melting ice when temperature drops below zero degrees. This research aimed to provide practical and efficient solutions for this application.
