Abstract

The invention provides a magnesium-based wear-resistant damping alloy material and a preparation method thereof. A matrix of the alloy material is provided with a stable plate compound, the damping function of an alloy is improved. The method has the advantages of simple process, low production cost, and suitability for industrial production. In the alloy material, a magnesium alloy is taken as the matrix, and compound complexes are uniformly distributed on the matrix of the magnesium alloy. The alloy material comprises the following chemical compositions in percentage by weight: 5 to 9 percent of Al, 2 to 4 percent of Sr, 2 to 3 percent of Sn, 0.5 to 3 percent of Fe, 0.03 to 0.09 percent of C, 0.5 to 1.5 percent of Dy, 1.1 to 3 percent of Y, 0.5 to 2 percent of La, and the balance of Mg.

Description

1. Technical field [0001] The invention belongs to the field of metal materials, and relates to a magnesium-based damping alloy material and a preparation method thereof. 2. Technical Background [0002] At present, in the field of metal materials, magnesium alloys are widely used as wear-resistant damping and vibration-reducing materials. [0003] Application No. CN200910023238.5 discloses a high-damping magnesium alloy containing quasi-crystalline reinforcement phase and its preparation method. The alloy composition and its weight percentage are: 0.9%-1.0% zinc, 0.15%-0.2% yttrium, 0.6% of zirconium. Magnesium and zinc are both industrial pure magnesium and industrial pure zinc; alloy elements yttrium and zirconium are added in the form of magnesium-30% yttrium and magnesium-30% zirconium master alloys respectively; through preheating, smelting and forming, a quasi-crystalline reinforcement is prepared Phase high damping magnesium alloy. However, the elements of this ma...
