Image forces on dislocations situated in  channels or in ’ precipitates, due to /’ interfaces, were investigated with regard to the anisotropic theory of elasticity. It was found that the results were affected by the values of the published elastic constants but, in most cases, the values of the image forces were comparable to those of the other forces which acted upon dislocations. At room temperature, the sense of the image forces did not depend upon the choice of elastic constants: dislocations in  were always attracted to the interfaces, and those in ’ were always repelled by them. However, the opposite conclusions could be drawn for a temperature of 1050C; depending upon the constants which were chosen.
