机械振动不仅可以产生噪声,且能引起金属材料的疲劳,影响精密机械和仪表的质量,使机器、仪表使用寿命缩短。为了控制机械振动噪声,上海钢铁研究所研制出一种AJ-1高阻尼减振合金,在现场试验中,荣获了“哑金属”的美称。 AJ-1合金以铁为主要成份,加入铬、铝、钛等合金元素,属于铁 Mechanical vibration can not only produce noise, and can cause fatigue of metal materials, affect the quality of precision machinery and instruments, so that the machine, instrument life shortened. In order to control mechanical vibration and noise, Shanghai Institute of Iron and Steel has developed a high damping damping alloy AJ-1, in the field test, won the “dumb metal” reputation. AJ-1 alloy with iron as the main ingredient, adding chromium, aluminum, titanium and other alloying elements, are iron
