THE DEFORMATION BEHAVIOR OF AZ31 MAGNESIUM ALLOY AT ELEVATED TEMPERATURES

Hot Deformation Mechanisms in AZ31 Magnesium Alloy Extruded at Different Temperatures: Impact of Texture

The hot deformation characteristics of AZ31 magnesium alloy rod extruded at temperatures of 300 °C, 350 °C and 450 °C have been studied in compression. The extruded material had a fiber texture with > < 0 1 10 parallel to the extrusion axis. When extruded at 450 °C, the texture was less intense and the > < 0 1 10 direction moved away from the extrusion axis. The processing maps for the material...

Mechanisms of Plastic Deformation in AZ31 Magnesium Alloy Investigated by Acoustic Emission and Electron Microscopy

Strain-induced Texture Development in the Magnesium Alloy Az31

Magnesium alloys are receiving increasing attention as a structural material in vehicles to reduce weight and increase fuel economy. Understanding the formability of lightweight alloys is one key to their successful introduction in vehicles. We present results of X-Ray diffraction and electron back-scatter diffraction texture measurements in as-cast and uniaxially compressed AZ31 for a variety ...

Anodizing of Magnesium Alloy Az31 by Alkaline Solution

-Anodizing of AZ 31 Mg alloy was investigate in 3M KOH solution for 10, 20 and 30min. at constant voltage of 5V. Atomic force microscope (AFM) used to investigate the roughness of anodic film formed on the surface while the scanning electron microscope (SEM) was used to determine the morphology of the anodic film, it was found that the roughness of the anodic film is mainly depend on the anodiz...

Application of T-shape Friction T test for Ti-6Al-4V Alloy at Elevated Temperatures

There are several parameters that have significant influence in metal forming process. One of the most important of them is friction coefficient. Friction can change the pattern of metal flow and the force needed for deformation. It is necessary to determine the friction coefficient to study the effect of friction on metal forming process. This study is concerned with numerical and experimental...
