一、引言优于以往的传统减振方式,新功能高阻尼减振合金能更积极主动地消音除噪,它可以直接用于振源或噪声源部位,简单而有效地控制声源,在减振方面取得令人满意的效果。在众多减振材料中,铁磁性合金Fe-Cr-Al有它独特优点:很容易加工成型,易于表面硬化,价格便宜,特别是极限使用温度高(≈400℃)并具有良好的机械性能和较高的减振性。本文探讨了Fe-Cr-Al合金的内耗Q~(-1)值随热处理温度变化的情况。
I. INTRODUCTION Outperforms the traditional method of vibration reduction in the past, the new high-damping damping alloy can more actively and silently eliminate noise. It can be used directly in the vibration source or noise source to control the sound source simply and effectively. Vibration achieved satisfactory results. Among the many damping materials, the ferromagnetic Fe-Cr-Al alloy has its unique advantages: it is easy to machine, easy to surface hardening, inexpensive, especially at extreme service temperatures (≈400 ° C) and has good mechanical properties and High damping. In this paper, the change of internal friction Q ~ (-1) value of Fe-Cr-Al alloy with heat treatment temperature was discussed.
