本研究は,電子・電気機器の配線材料として用いられてきた銅合金のさらなる高強度化,並びに高導電化の要求が高まることを背景として,既存の銅合金の特性を超える新たな合金開発を行う上で必須となる組織制御に関する基礎的知見を得ることを目的として実施した.本研究の成果の1つとして,未普及のCu-Co-Si合金が導電率特性において既存のコルソン(Cu-Ni-Si)合金を上回ることを明らかにし,実用化の可能性を見いだした.

In this study, electrical equipment wiring materials are used to improve the mechanical properties of electrical equipment, such as the high strength of electrical materials, and the requirements of high temperature and high temperature. in this study, the electrical wiring materials of electrical machinery and electrical equipment are highly strengthened, and the existing mechanical properties and properties of new alloys must be improved. The results of this study are as follows: 1% of the results of this study, the results of this study show that Cu-Co-Si alloy has not been widely used in the field of electrical properties of Cu-Co-Si alloy. In this study, the results of this study show that the results of this study have not been popularized. The results of this study show that there are significant differences in the performance of existing alloy (Cu-Ni-Si) alloy.
