Abstract
The GH4169 alloy steel is used to fabricate the gas turbine blades. It is required to withstand a gas stream temperature of 1600 °C and have a heat transfer rate of a domestic central heating system. For the regular grain growth under directional solidification condition, we study on how to select a single-crystal grain in the spiral grain selector. The purpose of the numerical simulation technique using the solidification process is not only to obtain the distribution of the temperature field or the flow field, but also to examine the single grain microstructure growing process based on the café module contained in Procast software. The simulation results show that the data basis for the analysis of the solidification of GH4169 alloy provides details on the grain morphology and a more accurate theoretical result for real as-cast products.
