シンバルの減衰特性に対する金属組織の影響

抄録

Cymbals are percussion musical instruments with a simpler structure than other musical instruments. Therefore, their material composition basically decides the sound quality and decay time rather than the skill of the player. In this study, specimens of cymbals to which Titanium, Zirconium and Iron were added were prepared. From the difference of diffraction rings by synchrotron radiation X-rays, the crystal structure of the specimens of cymbals prepared by various manufacturing processes was analyzed in order to investigate the relationship between the crystal structure associated with the material and manufacturing process used and the damping of the sound of cymbals. As a result, it was found that the changes in the crystal structure were due to the manufacturing process used. In addition, it was clarified that the changes affected the damping of the sound of cymbals.
