Preparation of Mn-Cu based damping alloy ingots coupled with strong magnetic fields shows many interesting phenomena on the solidification microstructure and crystal lattice. In this study, modified M2052 were prepared under different to investigate bulk behavior by using optical microscopy, scanning electron energy dispersive spectroscopy X-ray diffraction. Metallographic analysis reveals that deflection angle primary dendrite arm increases increase field strength. The distribution chemical composition characterized Fluorescence discloses Mn is enriched while Cu depleted along circumferential surface side, variation tendency changes from almost a level sloping line applied field. High have altered orientation γ-Mn dendrites (200) (111), coupling mechanism discussed experimental results.
