Abstract
Phases formed by isothermal diffusion in the Al–Zn–Sn ternary system have been studied at 270, 280, and 290°C for the three couples (Zn–10Sn)–Al, (Zn–28Al)–Sn, and (Al–10Sn)–Zn. The present work completes an earlier study using direct together with differential thermal analysis, and provides better understanding of isothermal equilibria. Comparing the results allows different possible diffusion paths to be proposed, and microprobe analysis of phases in isothermal equilibrium gives detailed information on the Al–Zn–Sn phase diagram.
