Microstructure and Plasticity of Hot Deformed 5083 Aluminum Alloy Produced by Rapid Solidification and Hot Extrusion / Badania Mikrostruktury I Plastyczności Odkształcanego Na Gorąco Szybko-Krystalizowanego I Wyciskanego Stopu Aluminium 5083

Abstract: The objective of the present study is to analyze the mechanical properties and thermal stability for rapidly solidified and extruded 5083 aluminum alloy (RS). Compression tests were performed in order to estimate flow stress and strain rate sensitivity relation for 5083 alloy in the temperature range of 20• C to 450• C. For the comparison purposes, conventionally cast and extruded industrial material (IM) was studied as well. Deformation tests performed at room temperature conditions show that rapidly solidifi… Show more

“…In correspondence to the conventionally cast material, 5083 RS alloy exhibit 45% higher yield strength and 25% higher ultimate tensile strength without significant decrease of plasticity [6]. Those features are direct results of the grain size refinement from an average diameter of ∼15 µm to ∼710 nm for conventionally cast and rapidly solidified alloy, respectively.…”
