| Abstract Scope |
Focused on the extrusion technology of high-performance aluminum alloy profiles with large complex sections, a series of work has been carried out. The hot deformation behavior of aluminum alloy was studied, the constitutive equations and processing maps were derived for several kinds of alloys. The effects of process parameters and die structures on deformation of extruded profiles were researched. The optimization methods for designing large and complex extrusion die structures were put forward. The welding behavior and microstructure evolution on welding interface in porthole die extrusion process were revealed, and a new no-dimensional prediction model for solid-state welding was proposed, in which the stress triaxiality, equivalent strain rate, temperature and contact time were coupled. Moreover, the isothermal extrusion, on-line quenching and stretching straightening technique were studied. A series of extrusion dies and profile products were developed and applied in the high-speed train, light weight vehicles and large-scale engineering structures. |
