 note = {Cu-Ag液体金属の自己拡散・相互拡散係数測定実験を拡散対法およびシアセル技法を使って宇宙実験用小型ロケットTR-1A-7の微小重力下で実施した。測定温度は1,433K、1,483K、1,533Kとした。10拡散対を含むシアセルを開発した。全部で30個の拡散対の液柱の作成と、この液柱の分割片への切断は問題なく行えた。純Cuと純Agに対して得られた自己拡散係数は液体の運動によって僅かに影響を受けた。これらのデータを、剛体球直径を熱力学的変分理論から計算する剛体球模型に基づく理論計算値と比較した。Cu-Ag液体金属における相互拡散データも流体運動の影響を受けた。この流体運動の原因について論じるとともに、微小重力下における拡散実験の完全な遂行にとって、特に混合液体の場合に、充分な注意を払わねばならないとの結論に達した。, The experiments of self and mutual diffusion coefficient measurements for liquid Cu-Ag alloys were performed under the microgravity of TR (Test Rocket)-1A-7 rocket with the use of diffusion couple method and shear cell technique. Measured temperatures were 1,433, 1,483 and 1,533 K. The shear cell containing ten diffusion couples was developed. It worked successfully to create the liquid columns of all 30 diffusion couples and cutting of these liquid columns into divided pieces without any troubles. The obtained self-diffusion coefficients for pure Cu and pure Ag were slightly spoiled by the effect of fluid motion. These data were compared with theoretically calculated values based on the hard sphere model, in which the hard sphere diameters are calculated from the thermodynamic variational theory. The present mutual diffusion data in liquid Cu-Ag alloys were also spoiled by the effect of fluid motion. Discussion is given to the cause of this fluid motion and it is concluded that careful attentions must be paid for the perfect performance of microgravity diffusion experiments particularly in the case of liquid mixtures., 資料番号: AA0029039022, レポート番号: NASDA-TMR-000013E},
