Development of age-hardenable wrought magnesium alloy

Multi-Objective Optimization of a Wrought Magnesium Alloy for High Strength and Ductility

An optimization technique is coupled with crystal plasticity based finite element (CPFE) computations to aid the microstructural design of a wrought magnesium alloy for improved strength and ductility. The initial microstructure consists of a collection of sub-micron sized grains containing deformation twins. The variables used in the simulations are crystallographic texture, and twin spacing w...

Structure–property relations of cyclic damage in a wrought magnesium alloy

The fatigue properties of an extruded Mg–3Al–0Mn magnesium alloy component were evaluated experimentally. Fully reversed, strain control fatigue tests were conducted on specimens extracted from regions with a varying grain size and texture. Scanning electron microscopy was employed to establish structure–property relations between microstructure and cyclic damage. Relations were drawn between m...

Magnesium Wrought and Fabricated Products Yesterday, Today, and Tomorrow

The developers of magnesium metal production were always interested in methods of producing alloys and products. Casting was the first major development in the production of structural parts, but rolling, forging and extrusion closely followed it. This paper reviews the tremendous historical developments in wrought products during the 1930’s and 1940’s. At the peak of magnesium production for W...

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 ...
