  Separating the strengthening phase in nickel–cobalt alloys doped with tantalum

  摘要：

  The hardness values of monophasic (fcc solid solution) and biphasic (fcc solid solution and separated phase) nickel-cobalt alloys doped with tantalum are determined using the Vickers method. Based on the resulting data, a composition-structure-hardness diagram is devised for the Co-Ni-Ta system.

  the Co–Nb-Re system were constructed at 1375 K and 1200 K by investigations of equilibrated alloys using electron probe microanalysis (EPMA), scanning electron microscopy (SEM), powder X-ray diffraction (PXRD), and differential thermal analysis (DTA). Phases take part in the following three-phase equilibria in the Co–Nb-Re system at 1375 K: (γСо+λ+λ′), (γСо+λ+(Re)), (λ+μ+(Re)), (μ+χ+(Re)), and (βNb+μ+χ)

• High-throughput measurement of the composition-dependent interdiffusivity matrices in Ni-rich fcc Ni-Al-Ta alloys at elevated temperatures

  Based on 9 groups of ternary Ni-Al-Ta diffusion couples, high-throughput measurement of the composition-dependent interdiffusivity matrices in Ni-rich fcc Ni-Al-Ta alloys at 1473, 1523 and 1573 K was performed in the present work by using the recently developed pragmatic numerical inverse method. The errors for the determined interdiffusivities were evaluated by a scientific method considering the error propagation. Since one set of adjustable parameters was utilized for all the diffusion couples at one temperature, the main interdiffusivity planes over the investigated composition range at three temperatures were then constructed. The reliability of the determined interdiffusivities was first validated by reproducing the experimental composition profiles and interdiffusion fluxes for each diffusion couple, then by directly comparing with the limit interdiffusivities calculated by the traditional Matano-Kirkaldy method, and finally by extrapolating ternary interdiffusivities into boundary Ni-Al and Ni-Ta binaries and comparing with the binary experimental data. The simulated/calculated diffusion properties can reproduce most of the experimental data, indicating that the interdiffusivities obtained via the pragmatic numerical inverse method are reliable. On the basis of the constructed main interdiffusivity planes at different temperatures, the composition-dependent activation energies for the main interdiffusivities were evaluated, from which the activation energy planes over the investigated composition range were then constructed.
