銅と銅合金 62 ( 1 ) 152 - 157 2023.11 [Reviewed]
Language:English Publishing type:Research paper (scientific journal) Publisher:日本銅学会 Joint Work
<p>A trade–off between mechanical strength and thermal conductivity prevents the achievement of higher thermal conductivity in copper alloys, while maintaining the high mechanical strength of copper at high temperatures, which can result in energy savings and a lower carbon footprint. Oxide dispersion–strengthened (ODS) Cu–<i>x</i>Y<sub>2</sub>O<sub>3</sub> (<i>x</i>=0, 0.5, 1, 2 wt%) alloys were prepared by mechanical alloying (MA) using a water–cooled high–energy ball milling machine and then sintered with a hot press. The indentation hardness of the sintered materials increased with the amount of Y<sub>2</sub>O<sub>3</sub>. Microstructural observations revealed that high strengths for the Cu– Y<sub>2</sub>O<sub>3</sub> ODS alloys was achieved by both oxide dispersion and fine grains. However, the thermal diffusivity was not simply dependent on the amount of Y<sub>2</sub>O<sub>3</sub>, which was higher in both Cu–0Y<sub>2</sub>O<sub>3</sub> and Cu–1Y<sub>2</sub>O<sub>3</sub> but lower in the others. Among the factors affecting the thermal diffusivity, the amount of impurities, such as Fe and Cr, introduced during the MA process are responsible for the higher values of thermal diffusivity in Cu–0Y<sub>2</sub>O<sub>3</sub> and Cu–1Y<sub>2</sub>O<sub>3</sub>. The obtained results indicate that ODS–Cu alloys fabricated by MA and sintering can overcome the trade–off between mechanical strength and thermal conductivity when the solute impurities are suppressed.</p>

<p>The purpose of the research unit UlCoMat (<u>Ul</u>trahigh-flux <u>Co</u>ncerting <u>Mat</u>erials) is creation of novel materials for advanced engineering systems, such as fusion and fission reactors, aerospace craft, rockets and chemical plants, based on understanding and control of the metastable phase and the self-organization induced in materials under extreme conditions. The UlCoMat will accelerate a paradigm shift from stable and resistant materials to metastable but adaptive ones. It focuses also on the science of life to seek long-life materials and a precise estimation of their existence for the development of robust engineering systems using the minimum materials compatible with economical and safety requirements.</p>

・本稿では,酸化物粒子の析出初期過程と高温での成長に着目した最近の研究による,酸化物粒子分散強化(ODS)鋼に関する知見を紹介。
・ODS鋼の酸化物粒子形成メカニズムの調査結果について,酸化物粒子の形成温度は合金中に含まれる酸素量や酸化物構成元素の添加量によっても容易に変化し,粒子サイズや分散状態に影響すると説明。
・酸化物粒子形成に及ぼす活性元素添加の効果として,通常の10倍量のY2O3,および酸化物粒子を微細化させるはずの活性元素の添加により,逆に粒子を粗大化させる結果となったと記述。
・軽水炉の過酷事故耐性の調査から,高温においては酸化物自体の安定性が粒子の成長に大きく影響する可能性に言及。 -
