Abstract The behavior of type‐304 stainless steel in a forced‐convection closed‐loop lithium system was investigated over a wide range of temperatures and velocities. Fundamental information concerning the mechanism for mass transport has been obtained by examining solution and deposition effects along flat plates. The rate‐determining process for solution is transport from the solid to the interface, whereas deposition rates are liquid‐phase controlled. Liquid‐phase mass transfer coefficients were correlated with a maximum deviation of approximately 15% by the use of von Kàrmàn's analysis of the turbulent boundary layer along a flat plate, combined with the Chilton‐Colburn empirical modification of the Schmidt group. In contrast no adequate model is available for the prediction of solution rate constants which must be determined experimentally. Mean values of the solution rate constants ranged from 0.154 to 0.750 × 10 −5 cm./sec. at temperatures from 510° to 612°C. These values are on the order of 10 3 smaller than corresponding liquid‐phase mass transfer coefficients.
