高性能铁基阻尼合金日本钢管公司开发成功一种新型高性能铁基阻尼合金，商品名称“ＤＡＷ”。ＤＡＷ合金管的噪音阻尼效果比高强度钢管要高１０倍，用作齿轮时其噪音阻尼效果要比ＳＣＭ４４０合金钢齿轮明显较好（减小１～６ｄＢ）。ＤＡＷ的阻尼机制是通过合金中位错的膨...
High-performance iron-based damping alloy Japanese steel company successfully developed a new type of high-performance iron-based damping alloy, trade name “DAW.” DAW alloy tube noise damping effect than high-strength steel pipe 10 times higher, when used as a gear noise damping effect than the SCM440 alloy steel gear was significantly better (reduced by 1 ~ 6dB). DAW damping mechanism is through dislocation of the alloy swelling ...
