Abstract

The triply periodic minimal surfaces (TPMS) structure is regarded as a highly promising artificial design, but the performance of composites constructed using this structure remains unexplored. Two porosity levels of Ti/Al interpenetrating phase composites (IPCs) were fabricated by infiltrating ZL102-Al melt into additive-manufactured TC4-Ti scaffolds with the TPMS porous in this study. The combination of the two-phase alloys exhibits structural integrity at the interfacial region, as evidenced by microscopic surfaces observed in uncompressed IPCs. Quasi-static compression tests were performed to demonstrate that the Young’s modulus, yield stress and maximum compressive stress of IPCs exhibit significant enhancement when compared to the individual TPMS scaffolds, due to the supporting and strengthening effect of the filling phase. In the compression process of IPCs, defects emerge initially at the interface between the ZL102 phase and TC4 phase, triggering the fracture and slip of the ZL102 phase, eventually propagating to involve fracture in the TC4 phase. The deformation behaviours obtained from numerical simulation were combined to support these experimental phenomena. The results show that the corresponding stress concentration region is the central region of the spiral surface, the maximum stress concentration region of the ZL102 phase is the same as that of the TC4 phase, and the ZL102 phase effectively shares part of the loading. The Ti/Al IPCs achieve equivalent load-bearing capacity through a simplified interpenetration process and the utilisation of lighter materials.

三重周期性最小表面（TPMS）结构被认为是一种非常有前途的人工设计，但使用这种结构构建的复合材料的性能仍有待探索。在本研究中，通过将 ZL102-Al 熔体渗入添加剂制造的具有 TPMS 多孔性的 TC4-Ti 支架，制造出了两种孔隙度的 Ti/Al 互穿相复合材料（IPC）。从未压缩的 IPC 中观察到的微观表面可以证明，两相合金的组合在界面区域表现出结构完整性。准静态压缩试验表明，与单独的 TPMS 支架相比，由于填充相的支撑和强化作用，IPC 的杨氏模量、屈服应力和最大压缩应力都有显著提高。在 IPC 的压缩过程中，缺陷最初出现在 ZL102 相和 TC4 相之间的界面上，引发 ZL102 相的断裂和滑移，最终扩展到 TC4 相的断裂。数值模拟得到的变形行为与这些实验现象相结合。结果表明，相应的应力集中区域是螺旋面的中心区域，ZL102 相的最大应力集中区域与 TC4 相的最大应力集中区域相同，ZL102 相有效地分担了部分载荷。通过简化穿插过程和使用更轻的材料，钛/铝 IPC 达到了同等的承载能力。

期刊介绍： Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
