摘要	The multi-blade casting technique used in fabricating blades by the superalloy K418B was investigated, which is more efficient and cost-saving in comparison with the traditional polycrystalline superalloy casting technique. In this work, the differences in microstructures and mechanical properties were analyzed by adjusting different thicknesses of the blades. The results of experimental studies and numerical simulations showed that the size of the gamma' phase and the stress rupture property were positively correlated with the thickness of the blades and that the cooling rate and the residual stress were negatively correlated with it. Additionally, the residual stress decreased from 200 to 50 MPa as the thickness of the blades increased which followed the same trends as the geometrically necessary dislocation (GND) density. This study provides guidance in the optimization of microstructure in multi-blade casting technology.
