Effect of ECAP process on deformability, microstructure and conductivity of AA5083 under thermal effect

Abstract

An alternate method of alloying is to use extreme plastic deformation on commercially available AA5083 to generate an ultrafinegrained microstructure. The objective of this approach is to improve mechanical characteristics without sacrificing corrosion resistance and biocompatibility. Anisotropy in mechanical properties is introduced by plastic deformation leading to the production of a distinct texture. This is a crucial concept to understand in order to build and model structural devices and components from a perspective based approach. The ultrafine-grained structure of AA5083, which was obtained by equal channel angular pressing, is examined in this work. Ex-situ and indirect in-situ thermal studies are used to supplement this investigation while the material is heat treated at different annealing temperatures. The results show that the elastic properties undergo very small change during the annealing process, in contrast to other parameters as thermal expansion, internal friction, or hardness. The strong relationship between the elastic anisotropy and texture highlights the importance and possibilities of using texture into the design and customization of mechanical characteristics. Pure deforms plastically in order to improve mechanical qualities while maintaining biocompatibility and corrosion resistance. Analysis of the materials elastic inhomogeneity and crunchiness in detail. In comparison to other characteristics like as inner conflict thermal enlargement or hardness, the results demonstrate that elastic properties barely marginally change during annealing. The microstructure fragmentation had no influence on the conductivity of the AA5083, which oscillated at 18 MS/m after the ECAP procedure. According to the findings, all deformed specimens strain hardening exponent and capacity were lower than they were in their as-received state. Investigated was the effect of size of grains on the strain hardening comportment of the ECAPed AA5083.
