Mechanical Property Evaluation of P/M (Powder-Metallurgy) Aluminum 7090-T7E71 Plate

Abstract

Mechanical property data were obtained for a single plate of powder- metallurgy (P/M) produced aluminum 7090-T7E71. Properties examined are tensile, compression, shear, bearing, smooth and notched fatigue, fatigue crack growth rate, and fracture toughness. Comparisons are made to other 7000-series ingot- metallurgy (I/M) produced aluminum alloys, more particularly, aluminum 7050. Results show the test material to be superior in strength, bearing, and shear properties than the majority of I/M 7000-series alloys. Improvements in both smooth and notched fatigue resistance are also realized over I/M aluminums 7050 and 7075 in their respective corrosion resistant tempers. Toughness and fatigue crack growth rate properties are inferior to several I/M produced 7000-series structural aluminum alloys. (Author)
