Rapidly solidified powder aluminum alloys; Proceedings of the Symposium, Philadelphia, PA, April 4, 5, 1984
Topics discussed include the need for rapidly solidified PM Al alloy development for aerospace and land vehicle applications, the solidification theory, and stereological characterization of porous microstructures. Papers treating the characterization of rapidly solidified materials, rapid solidification of highly undercooled Al powders, Al3Li precipitate modification in an Al-Li-Zr alloy, hardening mechanism in rapidly solidified Al-8Fe alloy, the fabrication of high-strength PM extrusions, hypereutectic Al-based alloys, the properties of Al alloys with 8-12 wt pct Fe and Al-Li-Be alloys, the microstructure of supercooled submicrometer Al-Cu alloy powder, and the influence of hydrogen on the ductility of 7091 and 7090 PM alloys. Attention is given to PM processing of Al alloy 7091, dynamic compaction of rapidly solidified Al alloy powders, the effects of alloy chemistry on superplastic forming of rapid solidification-processed Al-Li alloys, thermomechanical treatment of 2124 PM Al alloys, and a method for degassing evaluation of Al PM alloys. Studies concerned with high strength PM alloys, a technique for assessing the corrosion properties of Al PM alloys, the development of dispersion-strengthened Al alloys, the microstructure/mechanical property relationships for thermal treatments of Al-Cu-Mg-X PM Al alloys, PM and IM Al alloy forgings, the annealing behavior and tensile properties of elevated-temperature PM Al alloys, the effect of compositional changes on the microstructure and properties of rapidly solidified Al3-Li alloys and the use of rapid solidification for the development of 2XXX alloys.
