| 摘 要： | 采用永磁体搅拌的方法制备了AZ61镁合金。对其组织和腐蚀性能进行了研究。以电磁场和磁流体动力学原理为基础，分析了旋转永磁体磁场内液态金属的受力。结果表明：液态金属在永磁体搅拌过程中，受到大小和方向周期变化的径向力和切向力；在这一效果（即电磁振荡）的作用下。凝固组织发生变化，进而影响到基体的腐蚀性能.

| Abstract: | The microstructure and the corrosion property of AZ61 magnesium alloy stirred by permanent magnet (PM) were investigated. Based on the principle of electromagnetic field and magnetohydrodynamics, the force field of liquid metal in a PM field was analyzed. As a result, liquid metal in a PM experiences radial and tangential forces that are cyclically variational both in direction and magnitude. This phenomenon, namely electromagnetic vibration, influences matrix microstructure, subsequently affects corrosion property of the matrix. |
