Abstract

The microstructure resulting from diffusion reactions, at solid-state temperatures, in Ni/Sn couples has been studied by scanning electron microscopy (SEM) and energy dispersive X-ray (EDX). The Ni3Sn4 phase was the only reaction product which formed in the couples at temperatures from 150∘C to 220∘C. The growth kinetics of Ni3Sn4 layer followed the parabolic law with an apparent activation energy of 104kJmol−1. The effect of the atmosphere on the microstructure of the interfacial layer was investigated at 220∘C for a pressure of 10−8atm. A decrease in the growth rate of the phase layer was observed.
