轧制处理对生物医用Zn-Mg合金组织和性能的影响
|
摘要
采用金相显微镜、X射线衍射仪、扫描电子显微镜、万能材料试验机和电化学工作站等设备,分析和研究了轧制变形对生物医用Zn-Mg合金的显微组织及力学性能的影响。结果表明:铸态、轧制态的合金均由Zn和Mg2Zn11两相组成;在轧制变形过程中,物相未发生改变,抗拉强度逐渐提高,伸长率先提高后降低,耐腐蚀性能逐渐下降;随着轧制变形量的增加,晶粒沿轧制方向的变形程度逐渐增大,直至出现纤维状组织。在相同的退火条件下,轧制变形量越大的Zn-Mg合金,再结晶晶粒尺寸越细小、均匀。
The influences of rolling treatment on the microstructure and mechanical property of biomedical Zn-Mg alloy were studied by using metallographic microscope, X-ray diffractometer,scanning electron microscope, universal material testing machine, electrochemical workstation, and so on. The results show that both the as-cast and as-rolled alloys are composed of Zn and Mg2 Zn11. During the rolling process, the phases are not changed, the tensile strength increases gradually, the elongation firstly increases and then decreases, and the corrosion resistance decreases gradually. With the increase of rolling deformation, the deformation degree of the grains increases along the rolling direction until fiber tissue appears. Under the same annealing conditions, the size of the recrystallized grains is finer and more uniform after larger rolling deformation.
