Phase equilibria in Sn rich corner of Cu–Ni–Sn system

Abstract

Using the ‘solidification path’ technique, the liquidus projection of Sn rich corner of the Cu–Ni–Sn phase diagram was determined. Two quasi-peritectic reactions were found, which are related to the Cu–Sn and Ni–Sn binary eutectic reactions in this part of the system. The existence of a ternary Cu–Ni–Sn phase was confirmed. This phase was found to participate in both quasi-peritectic reactions.
