Mg-Y based alloys exhibit a promising combination of strength and deformability through tuning precipitation solute strengthening mechanisms tailoring the activity non-basal dislocations. Understanding sequence its dependence on Yttrium concentration in matrix will provide guideline for fine structure, morphology distribution precipitates alloys. In this paper, we explore behaviors Mg-11Y (wt%)...

We develop a geometry-based model from first-principles data for the interaction of solutes with a prismatic screw dislocation core, and predict the thermally activated cross-slip stress above room temperature in Mg alloys. Electronic structure methods provide data for the change in prismatic stacking fault energy for different possible fault configurations for 29 different solutes. The direct ...

Textures in the hexagonal metals have attracted significant interest over the years because of the use of some hexagonal metals and alloys, e.g. Zircaloy cladding for nuclear reactor fuels, Ti alloys for aerospace and aircraft industry, and Mg alloys for automobile and computer, communication and consumer electronic (3C) appliances. From a mechanistic point of view, hexagonal metals are differe...

Aluminum and aluminum alloys can be protected against corrosion by various methods of surface modification (e.g., metal finishing, anodizing, chromate conversion coatings, metallic cladding with Alclad, corrosion protection compounds, and solution phase inhibitors). The desire to deploy environmentally compliant multi-functional coatings has created the need for new concepts that can protect Al...
