Numerical Simulation of Directional Solidification Process of Single Crystal Ni- Based Superalloy Casting
Archives of Foundry Engineering
The analysis of influence of mould withdrawal rate on the solidification process of CMSX-4 single crystal castings produced by Bridgman method was presented in this paper. The predicted values of temperature gradient, solidification and cooling rate, were determined at the longitudinal section of casting blade withdrawn at rate from 1 to 6mm/min using ProCAST software. It was found that the increase of withdrawal rate of ceramic mould results in the decrease of temperature gradient and thedoi:10.1515/afe-2017-0061 fatcat:2pjswkrgejf6hi4ecnk4vlh6sq
