    Abstract:

    The effect of local loading traveling magnetic field on shrinkage cavity and porosity and mechanical properties of ZL205A sheet casts was studied. The microstructure and mechanical properties were analyzed by scanning electron microscope and electronic universal material testing machine, respectively. Results show that under travelling magnetic field, the shrinkage cavity and porosity decrease greatly, and the tensile strength, yield strength and elongation increase from 436.61MPa, 390.22MPa and 3.29% to 470.24MPa, 416.97MPa and4.15%, respectively. The tensile strength and yield strength increase by 33.63MPa and 26.75MPa, and the elongation increases by 26.14%.
