【摘要】 研制了Fe-5Al高阻尼合金,并在倒扭摆仪上检测了合金的阻尼性能。数据显示,随热处理温度的升高,阻尼性能逐渐升高,并在900℃下达到峰值。在900℃,不同保温时间处理的结果还表明,在0.5小时左右,合金的阻尼性能最好,对数衰减率超过90×10-3。当环境温度从50上升到500℃时,阻尼性能可以保持80%。更多还原

【Abstract】 Fe-5Al damping alloy was developed, and its damping capacity was tested by reversal torsion measurement. The results indicate that as the heat-treatment temperature become higher, the alloy damping capacity increases and reach the highest value at 900 centigrade. The alloy damping capacity is the highest when heated at 900centigrade for 0.5 hour and water-cooled, and the logrithmatic decrement value 6 is over 90 ×10-3. When the surrounding temperature increased from 50 to 500 centigrade, the damping capacity can be kept at 80%.更多还原
