Abstract

The invention discloses a method for improving the damping performance of high-strength ferro-manganese-based damping alloy, belonging to the field of damping alloy. The method can be used for remarkably improving the damping performance of high-strength ferro-manganese-based damping alloy and particularly the damping performance of high-strength ferro-manganese-based damping alloy under low strain amplitude. The high-strength ferro-manganese-based damping alloy contains the following elements in percentage by weight: 15-23% of Mn, 0-3% of Co, 0-1% of Si, 0-12% of Cr, 0-1% of Ti, 0-1% of Mg, 0-0.1% of C, 0-0.1% of N and the balance of Fe and unavoidable impurities. The method concretely comprises the following steps: firstly, carrying out solution treatment on ferro-manganese-based damping alloy at the temperature of 800-1100 DEG C for 10 minutes to 2 hours; then, carrying out aging treatment on the ferro-manganese-based damping alloy at the temperature of 50-400 DEG C for 10 minutes to 10 hours; finally, carrying out room temperature deformation at the deformation rate of 1-10%.

Description

technical field

[0001] The invention relates to a damping alloy, in particular to a method for improving the damping performance of a high-strength iron-manganese-based damping alloy. The method can significantly improve the damping performance of the iron-manganese-based damping alloy, especially its damping performance under low strain amplitude. Background technique

[0002] Damping alloys can convert mechanical vibration energy into heat energy and dissipate it in materials and the environment. Therefore, the use of damping alloy materials to design and manufacture various vibration source components can effectively reduce or prevent noise fundamentally. The development of high speed and strong power in modern national defense, industry and transportation not only creates an urgent demand for damping alloys, but also puts forward higher requirements for performance: not only requires alloys to have high damping performance, but also requires high Mechanical behavior. ...
