Single crystalline solidification with enhanced microstructure

Based on experience with the LMC (Liquid Metal Cooling) process, it is focused on the investigation of the newly developed FCBC (Fluidized Carbon Bed Cooling) process for the single crystalline solidification of superalloys. In comparison with commercially available investment casting processes it could be shown that FCBC benefits from a higher cooling potential. In combination with a dynamic baffle a higher axial temperature gradient will evolve. Objective is the improvement of the process understanding as well as the process optimization, carried out on a 10 kg prototype plant. A further point of interest is the exploitation of the increased microstructural homogeneity for alloy development.
