W pracy przedstawiono analizę wyników pomiarów i symulacji numerycznej rozkładu wartości temperatury W monokiystalicznym odlewie pręta z nadstopu niklu CMSX-4 wytwarzanego metodą Bridgmana. Opracowano model geometryczny zestawu modelowego i przestrzennego otoczenia formy ceramicznej oraz przyjęto warunki brzegowe. Ustalono wpływ kształtu modelu geometrycznego i zadanych warunków brzegowych na wyniki...
The paper is an attempt to determine the influence of manufacture conditions on the properties of CMSX-4 second generation single crystal superalloy castings. Single crystal rods with diameter of 12 mm and length 200 mm were casted by the vertical Bridgeman method in ALD Vacuum Technologies furnace. Pulling rates, typical for CMSX-4 nickel superalloy, were used: 4 mm/min and 5 mm/min. Using X-ray...
