Numerical Analysis of Az61 Magnesium Alloy Extrusion Process by Modified Equal Channel Angular Extrusion (ecae) Method
T. Bajor, M. Krakowiak, P. Szota, Czestochowa University of Technology, Czestochowa, Poland The paper presents the results of numerical modelling of AZ61 magnesium alloy hot deformation using modified ECAE method. The temperature-velocity conditions were analysed using FEM. The extrusion process was realised using the die with modified angular channel containing horizontal contracting zone in t...
متن کاملOptimization and utilization of semisolid casting process for semisolid welding of Al-6061 alloy
Semisolid processing is one of the modern routes in sound and near net shape parts production. Preparation of semisolid slurry using a cooling slope is increasingly becoming popular, primarily because of its simplicity in design and ease of control of the process. In this research, the microstructures of Al6061 semisolid alloy cast via a miniature cooling slope were investigated. The propertie...
متن کاملForming and Properties of Friction Stir Welding Process for Dissimilar Mg Alloy
For hot extrusions of magnesium alloy sheets, Dissimilar AZ80 and AZ31 were used, in which AZ80 was placed on advancing side and AZ31 on retreating side, using friction stir butt welding with different process parameters. Some defect-free welded joints with good weld surfaces could be obtained with some suitable welding conditions. The maximum tensile strength of welded joint which is 225.5 MPa...
متن کاملSubstructural Alignment during ECAE Processing of an Al-0.1Mg Aluminium Alloy
An investigation has been carried out into the microstructures developed during the early stages of equal channel angular extrusion (ECAE) in a polycrystalline single-phase Al-0.13Mg alloy, with emphasis on the substructural alignment with respect to the die geometry and the crystallographic slip systems, which is essentially related to the grain refinement and texture development during deform...
متن کاملWear Behavior and Microstructure of Mg-Sn Alloy Processed by Equal Channel Angular Extrusion
Mg-5wt.% Sn alloy is often used in portable electronic devices and automobiles. In this study, mechanical properties of Mg-5wt.% Sn alloy processed by Equal Channel Angular Extrusion (ECAE) were characterized. More precisely, its hardness and wear behavior were measured using Vickers hardness test and a pin-on-disc wear test. The microstructures of ECAE-processed Mg-Sn alloys were investigated ...
