摘要：Aging treatment is an important process of a new hot forming technology with synchronous cooling(HFSC) for heat-treatable, high-strength aluminum alloys. In this paper, it were carried out respectively experimental research both the artificial aging and natural aging, and subsequent performance testing and microstructure analysis were implemented to investigation the effect of different aging process on the final mechanical properties of AA2024. Research results show that, under the condition of forming temperature range from 475°C to 495°C, the mechanical properties of AA2024 which made by HFSC and after nature aging for 96 hours: yield strength, tensile strength and elongation ratio was up to 499.0MPa, 306.5 MPa and 19.1% respectively; For the artificial aging, at aging temperature of 190°C, aging time of 4∼8 hour, its yield strength, tensile strength and elongation ratio was up to 515.0MPa, 398.0 MPa and 11.1% respectively. © 2017 Trans Tech Publications, Switzerland.
