Abstract:

Wrought products from 170-lb aluminum alloy powder compacts have been fabricated and evaluated against three combinations of properties. Product forms included extrusions, die forgings, hand forgings, plate and sheet. Properties of interest included strength, ductility, fracture toughness, stress-corrosion cracking resistance, exfoliation corrosion resistance, and smooth and notched specimen fatigue performance.
