Abstract

The invention relates to structure and function integrated high-carbon damping vibration attenuation steel and a preparation method thereof, and belongs to the technical field of structure and function integrated engineering materials. The high-carbon damping vibration attenuation steel comprises the following chemical components in percentage by mass: greater than or equal to 1.2% of C, 1.5%-1.7% of Si, 0.20%-0.22% of Mn, 2.15%-2.25% of Ni, 0.25%-0.27% of Al and the balance of Fe. The preparation method of the high-carbon damping vibration attenuation steel comprises the processes of smelting and casting, rolling and heat treatment. Alloys of the steel are few in variety, low in alloy component content, relatively high in strength, relatively high in impact energy and excellent in vibration reduction performance, and can play roles in reducing the production cost and reducing vibration and noise. The high-carbon vibration attenuation damping steel has important significance in popularization and application of the structure and function integrated high-carbon vibration attenuation damping steel.

Description

technical field [0001] The invention relates to a high-carbon damping vibration-damping steel and a preparation method thereof, and belongs to the technical field of structural-function-integrated engineering materials. Background technique [0002] With the continuous development of science and technology, people's requirements for the working environment are also increasing, and noise, as a common source of pollution in the work, has been paid more and more attention by people. Key directions [Document 1: Du Guofang, Shan Changji, Cai Yan, Yang Haitao. Talking about vibration and noise reduction materials[J]. Science and Technology Innovation, 2018(32): 189-190]. Vibration and noise reduction in marine ships is a very important task, and the development of high-performance materials with vibration damping properties is an urgent problem to be solved. [0003] At present, the ideas of vibration and noise reduction can be divided into three categories: one is to isolate t...
