This study focuses on the preparation and characterization of zinc-based alloys containing magnesium, calcium, and manganese. The alloys were prepared by the melting of pure elements, casting them into graphite molds, and thermo-mechanically treating them via hot extrusion. The phase compositions of the samples were analyzed using X-ray diffraction technique and SEM/EDX analysis. The analysis confirmed that in addition to the Zn matrix, the materials are reinforced by the CaZn, MgZn and Mn-based precipitates. The mechanical properties of the alloys were ascertained by tensile, compressive, and bending tests, measurement of the samples microhardness and elastic modulus. The results indicate that an increase in Mn content leads to an increase in the maximum stress experienced under both tension and compression. However, the plastic deformation of the alloys decreases with increasing Mn content. This study provides valuable insights into the microstructural changes and mechanical behavior of zinc-based alloys containing magnesium, calcium, and manganese, which can be used to design alloys for specific biomedical applications.
本研究聚焦于含镁、钙和锰的锌基合金的制备与表征。这些合金通过纯元素熔炼、浇铸到石墨模具中以及通过热挤压进行热机械处理来制备。使用X射线衍射技术和扫描电子显微镜/能谱分析（SEM/EDX分析）对样品的相组成进行分析。分析证实，除了锌基体之外，材料还通过CaZn、MgZn和锰基析出物得到强化。通过拉伸、压缩和弯曲试验、测量样品的显微硬度和弹性模量来确定合金的力学性能。结果表明，锰含量的增加会导致拉伸和压缩时所经历的最大应力增加。然而，合金的塑性变形随着锰含量的增加而减小。本研究为含镁、钙和锰的锌基合金的微观结构变化和力学行为提供了有价值的见解，可用于设计特定生物医学应用的合金。
