摘要：The effect of high magnetic fields on the morphology of Al-Mn phases was investigated. It is found that the tropism and the alignment of Al(6)Mn precipitated phases become regular under high magnetic fields. The stronger the high magnetic fields, the more regular the alignment of Al(6)Mn precipitated phases. Al(6)Mn precipitated phases can generate oriented alignment and aggregation under high magnetic fields through the observation of the quenched microstructure of the Al-Mn alloy at different temperatures. Meanwhile, the number of Al(6)Mn phases increases continuously along with the increasing function time of high magnetic fields. X-ray diffraction also indicates that Al(6)Mn phases generate obvious tropism under high magnetic fields. The process of aggregation and growth of Al(6)Mn precipitated phases under the function of high magnetic fields after orientation were analyzed and discussed.
