摘要
研究了合金元素Ｚｎ、Ａｌ对新型减振降噪（高阻尼）铸造ＭｎＣｕ合金Ｍｓ点、减振性能及力学性能的影响，重点讨论了合金成分与减振性能ＳＤＣ及力学性能的关系。开发了高阻尼、高强度锰铜基阻尼合金ＺＭｎＤ１Ｊ，最优成分为Ｍｎ５０％、Ｚｎ５％、Ａｌ２％、余量Ｃｕ。典型性能：ＳＤＣ＝４４．５％，σｂ＝６７８ＭＰａ，δ＝２４．１％。ＭｎＣｕ系新型高阻尼功能材料的减振能力很高，同时力学性能可达ＺＧＤ３４５５７０的水平，可做结构材料使用。
The effects of the elements of zinc and aluminium on Ms point damping and mechanical property of MnCu alloy were studied. The relations between the alloy components with damping property and mechanical property were also discussed. So a kind of high damping, high strength MnCu matrix alloy (ZMnD1J) was exploited, whose best constituent is Mn 50%, Zn 5%, Al 2%, and Cu the balence. The typical properties SDC=44.5%, σb=678 MPa, δ=24.1%. The damping capacity of MnCu high damping material is high, meanwhile its mechanical properties are comparable with that of ZGD345570. It can be used as structural material.
