This nonsaturated condition can therefore differentiate between atomic planes with different solution rates, thus resulting in the observed anisotropic rate of solution of the germanium by the indium. Similar results have been noted in the solution of germanium and silicon by liquid aluminum. 8 As the temperature is 8 J. H.

Metals (to be published).increased, the solution rate is also increased, thus affecting the concentration gradient, which in turn increases the rate of movement of the interface.
