Effect of magnetic‐thermal coordinated control solidification on grains and porosities of a superalloy K4169
Year: 2024
Type: article
Abstract: Since the solidification structure of metals cast by conventional mold casting often has porosity defect, the combination of low voltage pulsed magnetic field and thermally controlled solidification was used to solve this defect. The combination method is called magnetic‐thermal coordinated control solidification. Pulsed magnetic field stirring can refine equiaxed grains, and the thermally controlled solidification method can eliminate the concentrated shrinkage cavity and reduce the dispersed shrinkage porosity. Thus, a superalloy K4169 with fine equiaxed grains, low content of dispersed shrinkage porosity and without concentrated shrinkage cavity defect is fabricated by magnetic‐thermal coordinated control solidification.
