Fracture Related Properties of X-2048-T851 Plate Including Specimen Size Effects on KIC.
Abstract
Mechanical property data were developed on a new aluminum alloy that is designated as X2048. The material, which was tested in the -T851 condition, was developed by its manufacturer, Reynolds Aluminum, to possess the strength, fatigue resistance, thermal stability and corrosion resistance of 2024-T851 and 2124-T851 while at the same time having increased toughness. It was shown that the strength and fatigue crack growth rate of X2048 are the same as 2024 and 2124 and that the X2048 possesses increased toughness. A limited corrosion study using precracked specimens showed the material to be unaffected by a salt water environment under the test conditions. The room temperature fracture test results were dependent on specimen size with larger specimens producing higher fracture toughness test data. Fracture toughness test data from the literature that was obtained using bend specimens were lower than the fracture toughness results obtained in this effort which employed compact tension specimens.
