Modeling Dissolution in Aluminum Alloys
Aluminum and its alloys are used in many aspects of modern life, from soda cans and household foil to the automobiles and aircraft in which we travel. Aluminum alloy systems are characterized by good workability that enables these alloys to be economically rolled, extruded, or forged into useful …

Dislocation -Obstacle Interactions in Aluminum Alloys
This thesis examines two types of dislocation-obstacle interactions: dislocation-particle interactions during creep deformation, and dislocation-loop interactions during deformation at room temperature. Dislocation-particle interaction studies in Al-Zn-Mg-Cu-Zr, Al-4Mg-0.3Sc, and Al-0.3Sc showed …

Deformation mechanisms in rapidly solidified aluminum alloys
… of four rapidly solidified (RS) and hot extruded aluminum alloys were investigated. Al-8.8Fe-3.7Ce (all compositions in wt%) and Al-8.9Fe-6.9Ce alloys produced from RS powders and two Al-8Fe-2Mo alloys one produced from RS ribbons and the other from powders, respectively, were creep tested in the …

Solidification cracking resistance of high strength aluminum alloys
… is used in the manufacture of high strength aluminum alloys uneven cooling rates at different parts of the ingot cause thermal stresses. Due to these thermal stresses, cracks are initiated at the startup stage which may propagate as the stress elevates. Hence the evaluation of fracture …

Microstructures and Properties of Rapidly Solidified Aluminum Alloys
… properties of microstructures produced in aluminum alloys that had been rapidly solidified by laser surface melting (LSM) or chill block melt spinning (CBMS). The alloys, all of which had the same solute content, had the composition Al-4.1Fe-0.6X (at.%), where X was Mo, Ce, Cr, V, or Zr. A …

Processing of Aluminum Alloys Containing Displacement Reaction Products
Aluminum and metal-oxide powders were mixed using mechanical alloying. Exothermic displacement reactions could be initiated in the powders either by mechanical alloying alone or by heat treating the mechanically alloyed powders. Exponential relationships developed between the initiation time of the …
