Spring'17 release of ME-databases

On some occasions that the material is not homogeneous or by typical examples of the cast materials with microsegregation, the existing composition gradients in the system can be disappeared with various time-temperature process cycle(s). Depending on the target, it might bring advantages or disadvantages for the material. It is possible to predict in advance the outcome and consequence of the process cycle(s).

With available data for chemical potentials and mobilities of the system components, the diffusion processes leading to the microstructure homogenization can be simulated. The concentration profiles for various annealing times at various temperatures can be estimated. Moreover, it is possible to perform the precipitates kinetics simulation in this changing environment to realize the consequential microstructural evolution.

Homogenization of Ni-based alloy PWA 1480: We use our thermodynamic and diffusion databases in “cell simulations” to predict requirements of homogenization heat treatments of cast alloys. The results of these “cell simulations” with ME-Ni database represent, for instance, the development of temperature-dependent element diffusion profiles between dendrite core and interdendritic area of a cast single-crystal Ni-base superalloy as a function of annealing time.

            

The metallographical picture of the PWA 1480 alloy structure with etched dendrite structure (bright cross-shapes) cut along (001) of the fcc matrix structure. A one-dimensional diffusion profile along the A-B cross-section simulated with MatCalc for the sample homogenized at 1300°C for various time periods are shown below. Sample is homogenized after 10 hours.
