    • Abstract
  • As a new aging treatment method, the nonisothermal aging process can effectively improve the comprehensive properties of aluminum alloys with high strength and toughness. The cases of nonisothermal aging process applied to aluminum alloys with high strength and toughness in recent years were briefly studied to summarize the characteristics of precipitates and the changes in mechanical properties and corrosion properties of aluminum alloy with high strength and toughness after different nonisothermal aging treatments. It is found that compared with the traditional aging process the efficiency of the nonisothermal aging process has been greatly improved. In addition, moreover, the types, sizes and distributions of matrix precipitates and grain boundary precipitates of aluminum alloy with high strength and toughness can be simultaneously controlled by a nonisothermal aging process so that aluminum alloy with high strength and toughness has mechanical properties similar to the T6 peak aging state and corrosion properties close to the T7x overaging state. Finally, future research and applications of nonisothermal aging processes for aluminum alloys with high strength and toughness are proposed.
