Comparison of Al/Ni and Co/Ni Interdiffusion Coefficients in Pseudobinary Sections of Ni3Al-Co alloys.

Popis výsledku v původním jazyce

Interdiffusion in Ni3Al intermetallic alloyed by 0 - 19 at % Co was studied in three pseudo-binary sections: c(Al) = 22, c(Co) = 3.5, and c(Co) = 16 (c in at. %). The experiments were carried out at temperatures between 900 and 1200 C. Since no detectable shift of tungsten inert markers was observed, it was concluded that the intrinsic diffusivities of element pairs with varying concentration (Al/Ni and Co/Ni) in respective pseudo-binary sections are approximately equal one to another. The interdiffusion in pseudo-binary alloys Al/Ni (c(Co) = const.) runs slightly faster than that in pseudo-binary alloys Ni/Co (c(Al) = const.). The relations between the measured interdiffusion coefficients in the Ni3Al-Co ordered gamma prime phase agree well with literature data for the interdiffusion coefficients in both pure gamma prime and Co alloyed gamma prime phases and also for the disordered Al-Ni and Co-Ni solid solutions. They are qualitatively explained by interaction between constituents an
