Although magnesium is one of the materials with the lowest density, its application is limited amongst other commercial materials due to insufficient strength. Generally, the strength of magnesium can be increased by introducing the Mg₁₇Al₁₂ phase into the structure with the addition of aluminum. In this study, as a different approach, Mg₁₇Al₁₂ particles were added to pure magnesium to form a composite structure. For this purpose, Mg composites with different Mg₁₇Al₁₂ contents were fabricated by powder metallurgy methods. Pure Mg and Mg₁₇Al₁₂ particles were mixed in a vacuum ball milling equipment for 1 h using zirconia balls to obtain the Mg metal matrix composite with homogeneously distributed intermetallic reinforcements. While for pure Mg powders, the sintering temperature was selected as 600°C, for Mg + Mg₁₇Al₁₂ mixtures, it was 420°C due to the eutectic transformation between Mg and Al. The sintering time and pressure of the Mg-based mixtures were held constant for 30 min and 50 MPa, respectively. All sintering processes were carried out under a 10^–2 Pa vacuum atmosphere. Microstructural characterization was performed using optical microscopy and scanning electron microscopy. The hardness and wear properties of the composites produced have also been studied. The hardness and wear resistance of composites increased significantly as the Mg₁₇Al₁₂ particle content increased. Although the particle-enhanced composite density increased from 1.72 to 1.92 g/cm³, a 2.4-fold increase in hardness and a two-fold increase in wear resistance was observed. This magnesium composite produced with a new design could be used in many different areas.

虽然镁是密度最低的材料之一，但由于强度不足，其在其他商业材料中的应用受到限制。通常，镁的强度可以通过添加铝将Mg ₁₇ Al ₁₂相引入到结构中来增加。在本研究中，作为一种不同的方法，将 Mg ₁₇ Al ₁₂颗粒添加到纯镁中以形成复合结构。为此，通过粉末冶金方法制造了具有不同 Mg ₁₇ Al ₁₂含量的镁复合材料。纯 Mg 和 Mg ₁₇ Al ₁₂将颗粒在真空球磨设备中使用氧化锆球混合 1 小时，以获得具有均匀分布的金属间增强体的 Mg 金属基复合材料。而对于纯镁粉，烧结温度选择为 600°C，对于 Mg + Mg ₁₇ Al ₁₂混合物，由于 Mg 和 Al 之间的共晶转变，烧结温度为420°C。镁基混合物的烧结时间和压力分别保持恒定 30 分钟和 50 兆帕。所有烧结过程均在 10 ^–2Pa真空气氛。使用光学显微镜和扫描电子显微镜进行微观结构表征。还研究了生产的复合材料的硬度和磨损性能。随着Mg ₁₇ Al ₁₂颗粒含量的增加，复合材料的硬度和耐磨性显着增加。尽管颗粒增强复合材料的密度从 1.72 增加到 1.92 g/cm ³，但观察到硬度增加了 2.4 倍，耐磨性增加了两倍。这种采用新设计生产的镁复合材料可用于许多不同领域。
