Abstract
A method for the determination of site preference of substitutional element s in intermetallic compounds is proposed. It is demonstrated in Ni3Al-X all oys that the ridge direction in thermal conductivity contours in the ternar y gamma' phase agrees with that of the solubility lobe of the gamma' phase in ternary phase diagrams. The ridce direction is a reliable indication of site preference of substitutional elements in intermetallic compounds. The present method is conveniently applied to a normal polycrystalline specimen with small size, and therefore, a versatile class of brittle compounds can be studied.
