Statistical analysis on static recrystallization texture evolution in cold-rolled AZ31 magnesium alloy sheet.
Cast AZ31B-H24 magnesium alloy, comprising Mg with 3.27 wt% Al and 0.96 wt% Zn, was cold rolled and subsequently annealed. Global texture evolutions in the specimens were observed by X-ray diffractometry after the thermomechanical processing. Image-based microstructure and texture for the deformed, recrystallized, and grown grains were observed by electron backscattered diffractometry. Recrysta...
متن کاملFATIGUE BEHAVIOUR OFA ROLLED AZ31 MAGNESIUM ALLOYS PREPARED BY EPAND BB CONDITIONS
Abstract: Rotating bending fatigue tests have been performed using smooth specimens of a rolled AZ31 magnesium alloy in laboratory air at ambient temperature. Fatigue strength and characteristic was evaluated and fracture mechanism was discussed on the basis fracture surface analysis. Electrical polishing (EP) as well as deep rolling (ball burnishing (BB)) U-notched specimens were performed on ...
متن کاملMechanical Characteristics on Fatigue Crack Propagation in Aluminium Plate
This paper present a mechanical characteristics on fatigue crack propagation in Aluminium Plate based on strain and stress distribution using the abaqus software. The changes in shear strain and stress distribution during the fatigue cycle with crack growth is identified. In progressive crack in the strain distribution and the stress is increase in the critical zone. Numerical Modal analysis of...
متن کاملStrain-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 ...
متن کاملAnodizing 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...
