DIFFUSION COEFFICIENT MEASUREMENT METHOD IN CONDUCTIVE MELT, AND DIFFUSION COEFFICIENT MEASUREMENT DEVICE IN CONDUCTIVE MELT

摘要

PPROBLEM TO BE SOLVED: To provide a method and a device which accurately measures a diffusion coefficient in conductive melt. PSOLUTION: Two conductive solid materials X and Y having composition constituents different from each other are held in a joined form so as to set the axial directions of the solid materials X and Y nearly parallel with a gravity direction in a vessel 1. Then, the solid materials X and Y are heated and melted with static magnetic field B applied in a direction nearly orthogonal to the gravity direction to form two conductive melts X' and Y' having composition constituents different from each other. Then, the conductive melts X' and Y' are maintained for a predetermined period of time, and cooled and solidified. PCOPYRIGHT: (C)2004,JPO&NCIPI
