Effect of Die Entry Angle on Extrusion Responses of Aluminum 6063 Alloy
Mechanical properties response of extruded 6063 aluminum alloy at varied die entry angle has been investigated. Plain carbon and tool steel dies with entry angles of 15, 30, 45, 60, 75 and 90 were simulated. Extrusion on the alloy was done at ambient temperature (37C) and the extruded samples from the various angles were subjected to selected service related mechanical tests and microstructural...
متن کاملDiscontinuous Dynamic Recrystallization during Accumulative Back Extrusion of a Magnesium Alloy
The study of nucleation mechanism of new grains during severe plastic deformation of magnesium alloys is of great importance to control the characteristics of final microstructures. To investigate the role of discontinuous recrystallization, a wrought AZ31 magnesium alloy was deformed by accumulative back extrusion process at 330 °C. The obtained microstructures were studied using optical and...
متن کاملModeling the Formation of Transverse Weld during Billet-on-Billet Extrusion
A comprehensive mathematical model of the hot extrusion process for aluminum alloys has been developed and validated. The plasticity module was developed using a commercial finite element package, DEFORM-2D, a transient Lagrangian model which couples the thermal and deformation phenomena. Validation of the model against industrial data indicated that it gave excellent predictions of the pressur...
متن کاملSurface Roughening Behavior of 6063 Aluminum Alloy during Bulging by Spun Tubes
Severe surface roughening during the hydroforming of aluminum alloy parts can produce surface defects that severely restrict their application in the automobile and aerospace industry. To understand the relation between strain, grain size and surface roughness under biaxial stress conditions, hydro-bulging tests of aluminum alloy tubes were carried out, and the tubes with different grain sizes ...
