Conditions of equilibrium at the interface between the solid and liquid phases in the course of directional solidification of a two-component melt and the rate of the decrease in the free energy of such a system in the case where diffusion in the solid phase can be neglected have been investigated. Using the previously suggested new boundary conditions for the diffusion equation, analytical expressions have been obtained for the shifts of the values of the concentrations in the liquid and solid phases at their interface, as well as for the solidification temperature as compared to the initial equilibrium values corresponding to a zero growth rate. It is shown that the magnitudes of these shifts are directly proportional to the solidification rate and are inversely proportional to the coefficients that describe the transport of atoms of various sorts through the interface. Using the above-mentioned boundary conditions, we have found an expression for the rate of the decrease in the free energy of the system under consideration and have shown that it can be divided into two parts, one of which is determined by the processes at the interface between the phases and the other is controlled by diffusion processes that occur inside the volume of the phases. The results are compared with those obtained in terms of a different approach, which is based on the determination of the balance between the changes in the free energy in the solid and liquid phases far from the solidification front. It is shown that both approaches yield similar results, so that in some cases they can be used as mutually complementary.

The partitioning ratios of 14C in solid, liquid, and gas phases were determined by batch sorption tests using 97 paddy soil samples. Each of the soil samples was suspended in deionized water containing [1, 2-14C] sodium acetate and shake-incubated for 7 days. More than 65% of the spiked 14C was released into the air, approximately 30% was partitioned into the solid phase, and the 14C remaining in the liquid phase was only a few percent. These results suggested that if the 14C incorporated into acetate migrated from a TRU repository site to paddy fields, most of the 14C would be released into the air and the rest would be partitioned into the soil phase. It is likely that microorganisms in the soils are responsible for these partitioning ratios because about 97% of the spiked 14C remained in the liquid phase in the microorganism-depleted sample.

Compositions of the equ‘diprated solid-liquid phases in the A1-CUA12, Al-Si and Pb-Sn Systems were exam ined by using Cameca microprobe microanalyser. Ali the solid and liquid phases were found to be uniform for the Systems. The m easured consentraticns of the solid and liquid phases in the A1-CU A12 system, the solid phases in the Al-Si system, the solid Pb and the liquid PbSn phases in the Pb-Sn system were in agreem ent w ith the phases diagram values. However the m easured compositions of the solid Sn phase and liquid Al-Si phases were found to be quite different from the phase diagram values. The difference for the solid Sn phase came from the semaring effect. and the liquid AlSi phase m ight came from the very different obsorbsi- tion coefficient for A lK a and S İK a lines. The corrected consantration of th e Iiquid AlSi phase was also in good agreem ent w ith the phase diagram values.
