Deformation of 8561 Aluminium Alloy during Mechanical Stir Processing at Higher Temperature

Abstract

<div class="section abstract"><div class="htmlview paragraph">The current research examines the structural and mechanical properties of sheets made from the 8561 aluminum alloy using the dynamic stir procedure. After being treated perpendicular to the direction of rolling, the compressive material characteristics of the strips were investigated at room temperature in the longitudinal and vertical dimensions relative to the treatment orientation. Tensile tests at the grain boundary were also performed at relatively high temperatures and different strain rates to assess the ductile mechanical properties of the crystallization substance and to ensure the distinctions from the parent material caused by the dynamic stir process. Tensile testing at temperatures and strain rates ranging from 380 °C to 780 °C was employed in parallel studies of the material's behavior at high temperatures. Electron microscopy was used to examine the fracture surfaces of specimens evaluated at various temperatures.</div></div>
