磁场强度对Al-5%Mn合金凝固组织的影响
Influence of Magnetic Field Intensities on Microstructure of Al-5%Mn Alloy
摘 要
在不同强度的磁场下进行了Al-5%Mn合金的凝固试验,利用光学显微镜和X射线衍射仪分别对合金凝固后的显微组织和物相进行了分析,研究了磁场强度对凝固析出相Al6Mn的影响.结果表明:未施加磁场时,析出相Al6Mn为枝晶状和条状,均匀地分布在基体组织中;施加强磁场后,析出相Al6Mn发生聚集和长大,并沿磁场方向形成取向,且随着磁场强度的增加,晶粒尺寸不断增大,取向程度不断增强.

Abstract
The solidification of Al-5%Mn alloy in magnetic field with different intensities was tested.In order to investigate the influence of magnetic field intensity on the deposite of Al6Mn phase,the microstructure and phase compositions patterns were tested by using the optical microscopy and X-ray diffraction (XRD).The results show that Al6Mn crystals aligned dendritic or strip-shaped structure and distributed uniformly in the matrix without magnetic field.While Al6Mn crystals unceasingly got together and grew up so as to form the orientation along the magnetic field direction in high magnetic field.With the increase of magnetic field intensity,the size of the Al6Mn crystals increased and the extent of the orientation of it also increased.
