【摘要】 使用片振法和日本３２５７型直流磁滞回线描绘仪，分别研究了铁基１２ＣｒＡＩＭｏＣ阻尼合金的应变振幅对阻尼本领Ｑ￣－１值的影响，以及碳含量对Ｑ￣－１值、磁滞损耗能ｗ、剩磁Ｂ．、磁感Ｂ＿１０（１０Ａ／ｃｍ场强下的磁通）和矫顽力Ｈ＿ｃ的影响：结果表明，在采用的应变振幅范围内，随振幅加大，Ｑ￣－１值增大约７０％～１００％；碳含量从０．００２％增加至０．０２６％，Ｑ￣－１值减小约５０％，ｗ值增大约１４０％，Ｂ，减小约２０％，Ｂ＿１０减小约８％，而Ｈ＿ｃ增大约４０％。更多还原

【Abstract】 The influence of strain amplitude on damping capacity Q￣-1 and the in-fluence of carbon content on Q￣-1,magnetic hysteresis energy loss W,remanent mag-netization B,magnetic induction B₁0.（in the 10 A/cm magnetic field intensity）and co-ercive force Hc of the iron based 12CrAlMoC damping alloy have been investigated by the resonance methOd and DC magnetic hvsteresis loop tracer,type 3257 made in Japan,respectively,It is found that in the range of the used strain amplitude,Q￣-1 in creases by 70%～100% with increasing the strain amplitude;when carbon content increases frorm 0.002% to 0. 026%,Q￣-1,B and B₁0 decrease by～50%,～20% and～8% respectively,but W and Hc increase by～140%and～40%respective-IV。更多还原
