Sample deformation due to solidification and concentration profiles after solidification were calculated with two commercial codes, MARC for a non-linear deformation analysis and ProCAST for a casting simulation. The calculated results of the sample deformation and of the concentration profile change on solidification were similar qualitatively to the experimental results, but the calculated value of the sample deformation was much smaller than that of the experiments. It was found that the flow due to solidification shrinkage should be considered., 資料番号: AA0029039020, レポート番号: NASDA-TMR-000013E}, title = {The solidification effects on diffusion experiments: Numerical simulation}, year = {2001} }
