The invention discloses a particle reinforced magnesium-based composite material and a processing method thereof. The particle reinforced magnesium-based composite material comprises a magnesium-aluminum alloy matrix and Al2Gd reinforced particles, the processing method comprises the following steps: smelting an alloy melt according to a certain component proportion, cooling the raw material melt to 670-690 DEG C, applying a spiral magnetic field to the raw material melt for electromagnetic stirring, and casting after stirring to obtain the particle reinforced magnesium-based composite material. According to the method for preparing the magnesium-based composite material by introducing the Al2Gd reinforced particles, the magnesium alloy can be reinforced, and the application scene of the magnesium alloy is expanded. 本发明公开了一种颗粒增强镁基复合材料及其加工方法，其中颗粒增强镁基复合材料包括镁铝合金基体和Al2Gd增强颗粒；加工方法包括：按照一定的成分配比熔炼合金熔体，将原料熔体降温至670-690℃，并对原料熔体施加螺旋磁场进行电磁搅拌，搅拌完成后进行浇铸，得到颗粒增强镁基复合材料。通过引入Al2Gd增强颗粒制备镁基复合材料的方法可以实现镁合金的强化，扩大镁合金的适用场景。
