| Research Abstract |
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.
