Development of GPa class damping materials for automobiles

我们发明的Fe-Al-Ni合金满足了汽车振动源附近使用的阻尼材料的要求。在本研究中，我们计划了解合金中高振动衰减的机制。此外，我们的目标是从所获得的结果中的合金的阻尼能力的改善。此外，我们试图通过使用特定的热机械处理的晶粒细化和织构控制来提高合金的延展性。

Fe-Al-Ni alloys which we invented satisfy the requirement for damping materials used near origin of the vibration in automobiles. In the present study, we plan to understand the mechanism of high vibration attenuation in the alloys. Moreover, we aim at the improvement of the damping capacity in the alloys from the obtained results. In addition, we try to improve the ductility of the alloys by grain refinement and texture control using a specific thermomechanical processing.
