Producing items that are of both high quality and long lasting is a difficult task for companies right now. There is a huge need for a wide range of engineering materials in today’s technologically advanced globe. The strength and qualities of the material determine the amount of material that may be used. Due to its excellent mechanical qualities and low density, aluminum-7075 alloy is mostly employed in transportation applications such as aerospace, marine, and vehicle production. This study addresses the fabrication and characterization of Al7075 semisolid metal matrix composite (MMC) reinforced with graphene nanoparticles. Samples are made with and without stirring graphene in aluminum-7075 at various temperatures of 800°, 830°, 860°, 890°, and 920°C. At these temperatures, the material is semisolid, so graphene is introduced and stirred into the molten liquid. The specimens meet the requirements of the American Society for Testing and Material (ASTM). The hardness, tensile strength, impact strength, and compression strength of various materials are evaluated and compared. Temperature lowers tensile strength, hardness, and compression. A scanning electron microscope (SEM) is used to examine the microstructure. The specimen is evaluated using ANSYS. Specimens with stirring have better mechanical characteristics. Graphene has high hardness and strength.

铝和石墨烯纳米粉基复合材料的力学行为

生产高质量和持久耐用的产品目前对公司来说是一项艰巨的任务。在当今技术先进的全球范围内，对各种工程材料的需求巨大。材料的强度和质量决定了可以使用的材料数量。由于其优异的机械质量和低密度，铝 7075 合金主要用于运输应用，如航空航天、船舶和车辆生产。本研究解决了用石墨烯纳米粒子增强的 Al7075 半固态金属基复合材料 (MMC) 的制造和表征。样品是在 800°、830°、860°、890° 和 920°C 的各种温度下，在铝 7075 中搅拌和不搅拌石墨烯制成的。在这些温度下，材料是半固态的，因此将石墨烯引入并搅拌到熔融液体中。样品符合要求美国测试与材料协会 ( ASTM)。对各种材料的硬度、抗拉强度、冲击强度和抗压强度进行评估和比较。温度会降低拉伸强度、硬度和压缩率。扫描电子显微镜 (SEM) 用于检查微观结构。使用 ANSYS 对试样进行评估。带搅拌的试样具有更好的机械特性。石墨烯具有较高的硬度和强度。
