Embodiment 1

[0028] The manufacturing method of the high damping Mg-Mn-Ce-Al-Zn-Y magnesium alloy is carried out as follows:

[0029]Step 1: In a vacuum melting furnace, melt the ingot and pass it into argon for protection, and add alloys according to the weight percentage Mn-1.37%, Ce-0.30%, Al-0.11%, Zn-0.35%, Y-0.64% element. Among them, Mg, Mn, Ce, Al, Zn, and Y are respectively added in the form of industrial pure magnesium, Mg-Mn master alloy, Mg-Ce master alloy, industrial pure aluminum, industrial pure zinc, and Mg-Y master alloy.

[0030] Insulate at 850°C and stir with electromagnetic induction to fully melt the raw materials. After the alloy is completely melted, continue to stand at 850°C for 10 minutes, and then water quench to room temperature.

[0031] Table 1 is the damping performance table of the high damping Mg-Mn-Ce-Al-Zn-Y alloy described in Example 1.

Abstract

The invention relates to a high-damping Mg-Mn-Ce-Al-Zn-Y alloy which comprises the following alloying element components, distributed in an alloy, in percentage by weight: 1.3-2.2% of Mn, 0.15-0.35% of Ce, 0.1-0.3% of Al, 0.25-0.55% of Zn, 0.5-1.5% of Y and the balance magnesium and inevitable impurities. The high-damping Mg-Mn-Ce-Al-Zn-Y magnesium alloy is prepared by the following process: adding the alloy elements in proportion, smelting and ingoting the alloy elements in vacuum, and carrying out water quenching on the smelted alloy to the room temperature, thereby obtaining the high-damping magnesium alloy. According to the process, by virtue of the synergistic effect in many ways, the alloy has relatively high damping capacity and very good plasticity. The damping capacity (Q<-1>) of the material prepared by the alloy can reach 0.2 at a room temperature when strain is 10<-3>. The preparation method is simple in process, is strong in transportability, is easy to operate, and is low in cost, so that the room-temperature damping capacity of the alloy is remarkably improved, and the applied range of the magnesium alloy is expanded.

Description

technical field [0001] The present invention relates to a high damping magnesium alloy and its manufacturing method, especially a high damping Mg-Mn-Ce-Al-Zn-Y alloy, the alloy is a six element magnesium alloy, including Mg, Mn, Ce , Al, Zn and Y six alloy elements, the high damping refers to the material when the strain is 10 -3 The damping performance Q that can be achieved when -1 ≥0.2. Background technique [0002] The development of modern weapons and equipment is becoming increasingly lightweight, high-speed and high-power, and the problems of vibration and noise caused by this have become particularly prominent. In addition, various vehicles and 3C products (Computer, Communication, ConsumptionElectronicsProducts) put forward more urgent requirements for structural lightweight and vibration and noise reduction. Therefore, metal structural materials with low density, high specific strength and high damping are one of the urgent material requirements in aerospace, ...
