The purpose of this study was two-fold: develop an aging curve for extruded 2195 aluminum and test the magnitude of the anisotropy in the extrusion throughout the aging process. Two aging curves were developed, one at 290oF and the other at 320oF, through hardness tests of aged samples. The hardness was found to change, from approximately 72 HRB to 90 HRB, within the first 6 hours and not change more than 2 HRB in the 42 hours following. It was determined that the 320oF temperature was more promising due to faster aging time, and the anisotropy study proceeded with that temperature. Samples were aged at 320oF for 6, 18, 28, and 48 hours and tensile tested. These aging times were chosen due to interesting characteristics found during aging. The researchers measured yield strength to determine the magnitude of the anisotropy throughout the aging time.
