Abstract

The kinetics of the solid-state reaction between Al and Pd is studied in the geometry of a lateral Al-Pd diffusion couple in the temperature range between 250 and 430 °C. The first reaction phase is the crystalline Al ₃Pd₂(δ) phase. After the growth of Al ₃Pd₂ reaches a critical length, the quasicrystalline decagonal Al₃Pd(γ') phase starts to grow in between the Al and the Al₃Pd₂ phases, and the Al₃Pd₂ and Al₃Pd phase continue to grow simultaneously. We have fitted this simultaneous growth with a recently proposed model of kinetic suppression on the basis of interfacial reaction barriers. Excellent agreement between the data and the model is found. From the analysis the effective interface growth constant for the Al₃Pd is extracted as a function of temperature.
