✦ Synopsis

With the Czochralski method of dynamic conditions have been reported(') while in growth there are no crucible restraints, and the solid-others little or no enhancement was found.( 8,g) A liquid interface should have little curvature. The most number of reviews of the subject supporting both probable source of dislocations is thought to be extremes have also appeared.(1°311) As a result of stresses set up on cooling in the regions of high such conflicting evidence, opinion remains sharply thallium concentration, which will have thermal divided as to whether diffusion rates can be materially expansion coefficients differing from those in the rest increased under dynamic conditions. The present of the mat'erial. effort was undertaken to consider the problem somewhat further making use of certain other published K. G. DAVIS data. The results may help to account for some of Department of Mines and P. FRYZUK the disparate experimental findings which have been Technical Xurveys reported. Physical Metallurgy Division Girifalco and Grimes(12) have treated the question Ottawa, Canada of diffusion in strained systems from a theoretical point of view and have shown that D P=I,S (1)
