Abstract

The invention discloses a preparation method of a manganese copper alloy material. According to the method, the process flow is shortened, the work efficiency is improved and the energy consumption is greatly reduced. The preparation method of the manganese copper alloy material comprises the following steps of: respectively preparing high-purity copper and manganese on the surface of stainless steel by an electro-deposition method; and then, performing thermal treatment in a tubular furnace in an argon shield condition to prepare a uniform manganese copper alloy material.

Description

technical field [0001] The invention relates to a method for preparing an alloy material, more specifically to a method for preparing a manganese-copper alloy material, and belongs to the field of material surface treatment. Background technique [0002] With the continuous development of industry, the problem of vibration and noise has become increasingly prominent, which not only affects the safety and service life of machinery and military equipment, but also has great harm to people's physical and mental health. Vibration and noise reduction has become an urgent problem to be solved. The most important and effective means to solve the problem of vibration and noise reduction is the use of high damping alloys. The relaxation movement of a large number of elastic twins in the manganese-copper alloy under the action of external force leads to energy dissipation. Therefore, the manganese-copper alloy has relatively ideal damping properties, and has been successfully used as ...
