Diffusion in Ni3Al-Co intermetallic.
Original language description
Interdiffusion in Ni3Al intermetallic alloyed by 0-19 at %Co was studied in the temperature range 900-1200 C. An attempt was made, to analyze the interdiffusion coefficient into intrinsic diffusivities of individual components.Since no detecatble shift of inert markers was observed, it was concluded that the intrinsic diffusivities of Ni,Al and Co are aproximately equivalent one to another. The interdiffusion in pseudobinary alloys Al/Ni runs slightly faster than that in pseudobinary alloys Ni/Co. Measurements of 63Ni radiotracer in Ni3Al-Co was measured at 1000-1200 C by residual activity method. Enhanced Ni volume diffusivites observed at 1200C are most likely due to short-circuit diffusion along interphase boundaries in beta + gamma with comma field. The grain boundary diffusion of 63Ni was estimated at 1000C and 1100C. It was in a good agreement with our previous measurements made with pure Ni3Al.
