近年来,针对噪音、振动问题,积极开发噪音控制技术、振动最佳的设计技术等。而减振、防振材料,减振钢板的需要量也日益增加。日本钢管公司以前生产的减振钢板“CALMA”,作为结构材料使用,尚存在强度和延性低以及减振性能下降等各种问题。为此,该公司最近研究成功作为结构材料比较易于使用的Fe-Al-Si系减振合金“NKK SERENA”。该减振合金具有以下特点:
In recent years, for noise and vibration issues, actively develop noise control technology, the best vibration design technology. The damping, anti-vibration materials, the demand for damping steel is also increasing. Japanese steel pipe company previously produced damping plate “CALMA”, as a structural material used, there are still low strength and ductility and vibration damping performance and other problems. For this reason, the company has recently successfully researched “NKK SERENA”, an Fe-Al-Si damping alloy which is relatively easy to use as a structural material. The damping alloy has the following characteristics:
