摘要
In the present study, we propose an aging parameter based on the aging temperature and the holding time, in order to quantify the degree of aging in aluminum alloys. The variations in hardness and tensile properties associated with different aging conditions were experimentally observed and expressed on a single curve according to the aging progression, which was quantitatively evaluated using the proposed parameter. The use of the proposed parameter provides a map of the hardness distribution and enables the determination of the optimum condition of the aging treatment, not only for maximizing the hardness value, but also for preventing the over-aging phenomenon.
