摘要： The present invention discloses a method for ultra-low temperature forming an ultra-thin curved part of a high-strength aluminum alloy. The method includes the following steps: step 1: selecting a cladding with a suitable thickness according to a wrinkle limit of a sheet; step 2: stacking the sheet and the cladding, then putting into a die, and closing a blank holder; step 3: filling a cavity of a female die with an ultra-low temperature medium to cool the sheet to below −160° C.; step 4: applying a set blank holding force by the blank holder, and enabling a male die to go down to form a thin-walled curved part; and step 5: opening the die and taking out the formed thin-walled curved part. The present invention utilizes the favorable formability of the high-strength aluminum alloy at the ultra-low temperature and the instability resistance of the thick sheet.

摘要： A manufacturing process of a high-strength aluminum alloy wire/strip includes the following steps: A. subjecting an alloy to smelting and spray forming to obtain a high-strength Al—Zn—Mg—Cu aluminum alloy blank; B. subjecting the blank to semi-solid upset forging to form an ingot; C. subjecting the ingot to hot extrusion and then to vacuum annealing to form a coiled material; D. subjecting the coiled material to hot continuous rolling to obtain a wire blank; and E. subjecting the wire blank to solution heat treatment, multiple stretching treatments, annealing, and multiple continuous stretching treatments to obtain the high-strength aluminum alloy wire/strip. The high-strength aluminum alloy wire/strip has the characteristics of fine and compact grains, uniform structure, clear grain boundaries, no precipitates, and no layered structure affecting the stretching performance.

摘要： Disclosed herein is a method of forming a high strength aluminum alloy. The method comprises heating an aluminum material to a solutionizing temperature for a solutionizing time such that the magnesium and zinc are dispersed throughout the extruded aluminum material to form a solutionized aluminum material. The method includes quenching the solutionized aluminum material to form a quenched aluminum material. The method also includes aging the quenched aluminum material to form an aluminum alloy, then subjecting the aluminum alloy to an ECAE process to form a high strength aluminum alloy.
