ac 米兰官网 No.47 Fusion of Core Technologiesac 米兰官网 and Elastic Anisotropy in Cu-Ni-Si Alloy Sheets

Hiroshi Kaneko, Tatsuhiko Eguchi, Hirofumi Inoue

The authors researched the influence of ac 米兰官网s in precipitation- hardened Cu-Ni-Si alloy sheets for springs on their elastic anisotropy. The ac 米兰官网s were measured by the X-ray pole figure measurement and the Electron Backscatter Diffraction (EBSD) method, and the Young’s moduli were measured by the resonance method and the tensile method at various composition ratios of several crystal orientations which developed during recrystallization. The Young’s modulus was the lowest when the Cube orientation{001}<100 was developed and the highest when the R orientation{ 231}<346 was developed. The difference was 30 GPa and above, and showed a good correspondence to the Hill model based on the ac 米兰官网 function (ODF). Different from the existing method of controlling the Young’s modulus by the increase of solution elements, this effect can broaden the variation of Young’s modulus without losing a good electrical conductivity. Therefore, this effect greatly enhances the flexibility of the design of springs for electric contact sections and contributes to the advancement in operations of connectors.
