Abstract

The invention discloses a method for preparing a high-performance magnesium alloy plate. The method comprises the following steps that a magnesium alloy plate is provided and subjected to homogenizingannealing; the magnesium alloy plate is subjected to pre-pressing deformation in the a direction of the plate, after first-time recrystallization annealing is conducted, the magnesium alloy plate issubjected to pre-pressing deformation in the b direction of the plate, the b direction of the plate is perpendicular to the a direction of the plate, and the magnesium alloy plate is subjected to second-time recrystallization annealing; and the magnesium alloy plate is subjected to pre-pulling deformation in the a direction of the plate, after third-time recrystallization annealing is conducted, the magnesium alloy plate is subjected to pre-pulling deformation in the b direction of the plate, and then the magnesium alloy plate is subjected to four-time recrystallization annealing. According tothe preparation method, the base surface structure can be weakened, the plate strength and the forming performance are high, the finished product yield is high, and the comprehensive cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of processing magnesium alloy plates, in particular to a method for preparing high-performance magnesium alloy plates. Background technique [0002] With the development of automobiles, rail transit, and aerospace products in the direction of low energy consumption, there is an urgent need for high-performance lightweight materials. As one of the lightest metal structural materials, magnesium alloy has the advantages of high specific strength, high specific stiffness, and excellent damping performance. Important material selection. [0003] Among metal structural materials, the proportion of plastic processed products accounts for more than 70%. Deformed magnesium alloy plates are the same as steel and aluminum alloy deformed products, and their development and application are crucial to the popularization and application of magnesium alloys. However, wrought magnesium alloys belong to the hexagonal close...
