Abstract

The invention discloses a high-intensity high-damping deforming magnesium alloy with rear earth yttrium, which is characterized by comprising the following components by weight percent: 2.9-3.1 percent of Al, 0.9-1.1 percent of Zn, 0.5-2 percent of Y, 0.29-0.31 percent of Mn and the rest of Mg and unavoidable impurities. The high-intensity high-damping deforming magnesium alloy with rear earth yttrium can greatly increase the mechanical property and the damping performance of the high-intensity AZ series deforming magnesium alloy, successfully solve the conflict of the mechanical property andthe damping performance of the magnesium alloy and satisfy the actual requirements for a high-intensity high-damping light-weight material in the fields of very high-speed trains, automobiles, aerospace, national defense war industry, and the like, moreover, the magnesium alloy material has lower cost, and a technical device is the normal universal device with strong portability and easy operation.

Description

technical field [0001] The invention relates to an alloy material, in particular to a magnesium alloy material added with rare earth yttrium to improve alloy strength and damping. Background technique [0002] In recent years, as the automobile industry, rail transit, and aircraft have become increasingly lightweight, high-speed, and high-power, more urgent requirements have been put forward for reducing product weight, improving portability, reducing energy consumption, and reducing vibration and noise. . However, traditional steel materials have gradually been unable to meet their needs, so it is urgent to find a metal structure material with low density, high strength and good damping performance. [0003] Among many metal structural materials, pure magnesium has a series of advantages such as low density, strong damping, vibration and noise reduction capabilities, high specific strength, and good electromagnetic shielding performance, which has attracted extensive resea...
