Abstract

Non-parabolic growth of intermediate phases in CuSn binary diffusion couples has been observed at 220° C. The deviation from parabolic behaviour may be attributed to grain boundary diffusion. Diffusion coefficients for both the∈-(Cu3Sn) andη-(Cu6Sn5) phases are typically of the order of 2×10−11 cm2 sec−1, and are in general agreement with other published values.
