摘　　要：镁合金系金属间化合物的强化机理主要有基体强化和晶界强化两种。目前在镁合金研究领域应用较为广泛的计算机模拟方法有第一性原理方法、蒙特卡罗方法、分子动力学方法等,介绍了国内外计算机模拟镁及镁合金微观组织结构的研究进展,探讨了镁合金模拟的发展方向。Magnesium alloys are typical materials which are used in extensive area. The matrix strengthening and grain-boundary strengthening are used generally in magnesium alloy intermetallics. At present, several computer simulation methods are employed in theory, such as first-principles method, Monte Carlo method, molecular dynamics method and the finite element method, and so on. In this paper, the microstructures and properties of magnesium alloys are introduced. Some simulation results about research progress of magnesium are presented. Finally, the directions of simulation development in magnesium alloys are discussed.
