Abstract

The invention relates to a high-damping high-strength Mg-Ca-Sn magnesium alloy and a preparation method thereof. According to mass percentage, the components include: 0.1-0.6% Ca, 0.1-0.4% Sn. The balance is Mg and unavoidable impurities such as Fe and Si, and the total impurity content is ≤0.05%. The invention utilizes the multi-element micro-alloying method to improve the damping performance and mechanical performance of the magnesium alloy.

Description

technical field [0001] The invention belongs to the field of high-damping alloy materials and their preparation, and in particular relates to a high-damping and high-strength Mg-Ca-Sn magnesium alloy and a preparation method thereof. Background technique [0002] The damping performance of materials has the functions of reducing vibration, reducing noise and improving fatigue performance, and there are strict requirements on it in practical applications. With the development of modern high technology, materials are required to have good damping, vibration and noise reduction capabilities. At present, the structural materials used in aerospace, aviation, automobile and other transportation fields, such as aluminum alloy, titanium alloy and steel, etc., have poor damping performance (quality factor Q -1 <<0.01), leading to vibration fatigue cracks in some parts and failure of instrumentation, threatening the reliability and life of the system operation. Failure analysi...
