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.
期刊介绍：
Materialwissenschaft und Werkstofftechnik provides fundamental and practical information for those concerned with materials development, manufacture, and testing.
Both technical and economic aspects are taken into consideration in order to facilitate choice of the material that best suits the purpose at hand. Review articles summarize new developments and offer fresh insight into the various aspects of the discipline.
Recent results regarding material selection, use and testing are described in original articles, which also deal with failure treatment and investigation. Abstracts of new publications from other journals as well as lectures presented at meetings and reports about forthcoming events round off the journal.
