Keywords銅合金 / ヘテロナノ組織 / 変形双晶 / 単純強圧延
Outline of Research at the Start

本研究では,代表的な2種類の電子機器用銅合金(固溶強化型Cu-Zn系合金,析出強化型Cu-Ni-Si系合金)をモデル材として用い,新技術”ヘテロナノ(HN)組織”と,従来の”固溶強化”と”析出強化”を組み合わせ,次世代技術を支える銅合金設計指針の構築を目指して,以下の項目について評価検討を行う.

i. HN組織の組織学的パラメータと機械的・電気的特性の関連性の解明
ii. HN組織導入のための合金組成,加工条件の最適化
iii. Cu-Zn系合金のHN組織化による特性向上
iv. Cu-Ni-Si系合金のHN組織化による特性向上

Outline of Final Research Achievements

Heterogeneous nano (HN) structure consisting of nanometer-ordered deformation twin domains, low-angle lamellae, and shear bands was introduced into precipitation- and solution-strengthening Cu alloys by simple and heavy cold rolling to achieve an ultra-fine-grained structure and ultra-high strength without deteriorating electrical conductivity, which is the most important property of Cu alloys for electronic devices. For precipitation-strengthening alloys, a strength approximately 1.5 times higher than that of commercial alloys was achieved without compromising the conductivity by optimizing the thermomechanical treatment process. In the case of solution-strengthening alloys, the addition of trace alloying elements and improvements in the rolling process have resulted in strengths nearly twice that of conventional alloys. Based on the obtained results, a design guideline for ultra-high-strength Cu alloys utilizing the HN structure was proposed.

Academic Significance and Societal Importance of the Research Achievements

近年の電子機器の小型化によって,それらに使用される銅合金には,高強度と高導電性という相反する特性を極めて高いバランスで達成する事が要求されている.しかし,既存の強化機構(析出強化,固溶強化,加工強化,結晶粒微細化強化)とその組み合わせでは,既に要求特性に応えることが難しくなっている.本研究では,申請者らが新たに見いだしたヘテロナノ組織を銅合金に導入することで,これまでの常識を越える特性を有する銅合金の創成に成功した.これは,現状限界に達していた銅合金の性能向上へのブレークスルーとなり得る.また,ヘテロナノ組織は極めて平易な加工法によって導入可能なため,早期の社会実装も期待できる.
