• 一般注記: The solidification effects on liquid diffusion measurements were investigated experimentally. Diffusion couple samples were melted, and solidified under various cooling conditions. The concentration distributions were analyzed after solidification. It was found that the volume change effect can be avoided at low cooling rate and this condition is preferable for self- and impurity diffusion measurements, in which the segregation effect doesn't need to be considered. However, in order to avoid the segregation effect for mutual-diffusion measurements, diffusion measurements using the long capillary method should be conducted as follows: The diffusion sample must be cooled rapidly in order to avoid the segregation effect, and the concentration profile must be analyzed near the surface in order to avoid the volume change effect on solidification.; 資料番号: AA0033133015; レポート番号: NASDA-TMR-010019E
