Abstract

The invention provides a Mn-Cu-Al thermosensitive damping alloy material and a preparation method thereof. The preparation method of the Mn-Cu-Al thermosensitive damping alloy material comprises the following steps: S1, calculating according to the atomic percent of Mn-Cu-Al to obtain the mass percent of Mn-Cu-Al; S2, weighing the corresponding weights of Mn pieces, Cu blocks and Al blocks according to the calculated mass percent of Mn-Cu-Al; S3, smelting the Mn pieces, the Cu blocks and the Al blocks to obtain uniform-component cast ingots; S4, hot rolling the smelted cast ingots into sheets; and S5, quenching the sheets with water and removing oxide scales of the sheets to obtain a Mn-Cu-Al alloy. Through the preparation method, the alloy is prepared into a series of thermosensitive elements which are thermosensitive to different temperatures in a range of room temperature to 140 DEG C by controlling different aging temperatures and different ageing times.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a Mn-Cu-Al heat-sensitive damping alloy material and a preparation method thereof. Background technique [0002] The manganese-based alloy with high manganese content will undergo paramagnetic → antiferromagnetic transformation and martensitic transformation in a certain composition range during cooling from high temperature, and antiferromagnetic → paramagnetic transformation and martensitic transformation will occur during the heating process. Inverse martensitic transformation. γMn-Cu (manganese-gold) alloy is a typical antiferromagnetic alloy. Its martensitic phase transition temperature and antiferromagnetic phase transition temperature are coupled with each other within a certain composition range, and it has good damping performance and machinability. After aging, local Mn-rich regions and Cu-rich regions will be formed. [0003] With the continuous development of scie...
