POWDER METALLURGICAL PROCESSING provides much finer and homogeneous microstructure, better mechanical properties, and near-net shape parts producibility for aluminum alloys in comparison with ingot metallurgy (I/M). In addition to the conventional blending and consolidation of elemental or prealloyed powders into near-net shape parts, emerging processes such as mechanical alloying and rapid solidification (RS) create composite powders that upon subsequent consolidation provide significant improvements in room and elevated-temperature strength, fracture toughness, fatigue life, and corrosion resistance. 70 plus occurrances of 6061 in text, tables, and curves throughout article.
