【摘要】 采用倒扭摆法,研究了添加Al对M2052阻尼合金阻尼性能的影响。结果表明:添加1%、2%的Al能够提高M2052合金在室温下的阻尼性能,添加3%的Al,阻尼性能下降;添加1%、2%的Al,M2052合金的阻尼性能随温度的升高下降加快,添加3%的Al,M2052合金的阻尼性能随温度升高急剧下降。更多还原

【Abstract】 The effects of adding Al on damping capability of M2052 alloy as-annealed were studied by olympus optical microscope and reversal torsion pendulum.The results show that,adding 1%Al and 2%Al can improve the damping capability of M2052 alloy at room temperature,adding 3%Al,the damping capability decreases;adding 1%Al and 2%Al,the damping capability of M2052 alloy decreases faster with the increase of temperature,adding 3%Al,the damping capability of M2052 alloy decreases rapidly with the increase of temperature.更多还原
