The homogeneity ranges of the delta (δ) and gamma (γ) phases of the Ni-Zn binary system grown by the reaction couple method

Abstract

When investigating the diffusion layers grown by the reaction couple method at the Ni-Zn interface at 350 and 400 ‡C, the homogeneity ranges of the 5 and γ phases were found to be 87.5 ± 0.2 to 89.0 ± 0.2 at. % Zn and 73.1 ±03 to 86.2 ± 0.3 at. % Zn, respectively. Chemical compositions of the phases investigated can therefore be expressed in the simplest form as δNiZn7 to 8 and γNiZn3 to 6.
