Abstract
Aluminum alloy atomized or other powder is compacted and shaped into a useful article including heating the compact rapidly by induction heating techniques. Such rapid induction heating results in improved strength or toughness properties without substantial penalty in elongation, thereby rendering the product so produced more useful in high strength applications. The product so produced may be subsequently shaped by forging, extruding or rolling processes.
