综述组合思想在二元和多元钛合金体系中的应用。对于某个确定的钛合金系,组合方法能全面地研究其中的相变规律和组分对合金力学性能的影响。以组合思想为指导,选择Ti-Al-V系和Ti-Al-V-Cr-Mo 2个典型合金体系,利用IM100旋转多靶离子束沉积系统制备出合金元素含量梯度变化的钛合金组合芯片,通过X射线衍射仪(XRD)、原子力显微镜(AFM)、X线光电子谱仪(XPS)表征薄膜态样品库的存在相、形貌和表面元素的化学状态。利用纳米压痕测试钛合金薄膜的硬度,并从Ti-Al-V系和Ti-Al-V-Cr-Mo系中发现2个力学性能最佳的合金组分。
Summarize the Application of Combination Theory in Binary and Multivariate Titanium Alloy System. For a certain titanium alloy system, the combination method can comprehensively study the phase transformation and the influence of the components on the mechanical properties of the alloy. Under the guidance of combination theory, two typical Ti-Al-V and Ti-Al-V-Cr-Mo alloy systems were selected, and the titanium alloy composite chip with gradient variation of alloying elements was prepared by IM100 rotating multi-target ion beam deposition system The X-ray diffraction (XRD), atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS) were used to characterize the chemical and physical properties of the thin film samples. The hardness of the titanium alloy film was measured by nanoindentation and two alloy components with the best mechanical properties were found from the Ti-Al-V and Ti-Al-V-Cr-Mo systems.
