Influence of Microgravity on the Freezing of an Eutectic Volume

Diffusion-coefficient measurements in liquid metallic alloys

“…It would be interesting to examine whether the constancy of the diffusion coefficient along the phase boundary in these systems is a mere coincidence or is valid in general. [27] 5 ϫ 3 ϫ 225* 0.1 5.36 ϫ 10 Ϫ3 Sato and Ohira [10] *Rectangular cross section. We also checked the results of the diffusion coefficient values through independent measurements of the condition for transition from a single phase to a coupled growth, which is given by [30,31,32] [5]…”

“…We may, thus, examine different values of the diffusion coefficient in the liquid in the Al-Cu system presented in the literature, [4,7,8,10,26,27] in which different-diameter samples were used. All the measured values of the diffusion coefficient in hypoeutectic Al-Cu alloys, presented by different research groups using vertically upward solidification in the Bridgman apparatus, are summarized in Table I.…”
