摘要
Fe-Mn基阻尼合金是近些年来发现的一种新型金属阻尼材料。以Fe-Mn基阻尼合金为研究对象,对经不同固溶温度(800、900、1 000℃)处理后的Fe-Mn、Fe-Mn-P阻尼合金的力学性能、耐蚀性能、阻尼性能进行了测试,利用EBSD进行了显微组织结构表征。结果表明:磷元素添加提高了阻尼合金的屈服强度,有利于提高合金的耐腐蚀性能,但极大地恶化了阻尼合金的低温韧性,降低了阻尼合金的阻尼性能。在800℃固溶状态下,Fe-Mn-P合金阻尼性能最佳,随着固溶温度的升高,Fe-Mn-P阻尼合金强度降低,阻尼性能降低;ε/ε和ε/γ界面密度是影响FeMn-P阻尼合金阻尼性能的重要因素。
Fe-Mn damping alloy is a new type of metal damping material discovered in recent years.This paper takes Fe-Mn damping alloy as the research object.The mechanical properties,corrosion resistance and damping properties of the alloy were tested,and the microstructure was characterized by EBSD.The addition of phosphorus increases the yield strength of the damping alloy,which is beneficial to improve the corrosion resistance,but greatly deteriorates the low-temperature toughness and reduces the damping.With the increase of solid solution treatment temperature,the strength and damping of Fe-Mn-P damping alloy decrease;the damping of Fe-Mn-P alloy is the best at 800℃.ε/εandε/γinterface density is an important factor affecting the damping of Fe-Mn-P alloy.
