Mechanical Property Data Base from a Cooperative Program on First Generation PM (Powder Metallurgy) Aluminums

摘要

Development of a mechanical property data base on first generation P/M structural aluminum alloys is detailed. P/M aluminum alloys tested were 7091 forgings, 7090 forgings, IN9021 forgings, 7091 extrusions, 7090 extrusions, IN9021 extrusions, 7091 plates, 7090 plates, and 7091 sheets. Basic mechanical property data consisted of tension, compression, shear, bearing and fracture toughness. Fatigue data was developed for both smooth and notched specimens. Constant amplitude fatigue crack growth rate data were obtained for all materials and spectrum tests were performed on most products. Corrosion characteristics were also obtained. All data developed by the participants are detailed. (Author)
