タイトル（掲載誌）宇宙航空研究開発機構研究開発報告 = JAXA Research and Development Report: Modeling and Precise Experiments of Diffusion Phenomena in Melts Under Microgravity
一般注記The shear cell method for the diffusion experiment on the ground is being studied to establish the reliable experimental process of diffusion in liquids even on the ground and to present the reference data for experiment under microgravity. The adopted systems are liquid Ge-Sn and Ge-Si systems. It is not always easy to measure diffusion coefficients in these systems, because those solid-liquid coexisting regions are wide. The wide solid-liquid coexisting region causes the segregation problems on the sample preparation, and the analysis of concentration profile. The methods for obtaining homogeneous pieces of diffusion couple sample were investigated and a concentration profile after the diffusion experiment was analyzed accurately. Shear cell experiments of Ge-Sn system were performed in the temperature range, 750 - 1,300 K, as a prototype experiment. Moreover, the method of the concentration analysis of the Ge-Si sample was studied.
