Tensile and Strain-Controlled Fatigue Data for Certain Aluminum Alloys for Application in the Transportation Industry

Monotonic and cyclic strain-controlled fatigue tests were conducted at room temperature on several heat-treatable and non-heat-treatable aluminum alloys of interest to the transportation industry. Extrusion, forging, plate, and sheet product-forms were tested. Various monotonic and cyclic fatigue properties are furnished, and the respective strain-life curves are compared. In general, materials with strong monotonic strain-hardening tendencies are also shown to exhibit marked cyclic hardening.
