Abstract

Mg/Ti bimetal composites were fabricated by ultrasonic-assisted solid−liquid compound casting with an additively manufactured Ti-based pyramidal lattice structure at the interface. The Taguchi method was carried out to optimize the lattice parameters. The optimized geometric parameters include: the strut diameter (d) is 1 mm, the ratio of strut length to diameter (l/d) is 3, and the ratios of the upper and lower node to diameter (d₁/d and d₂/d) are 2.5 and 2.5, respectively. The ratio of strut length to diameter is the most significant factor affecting failure strength. The failure strength of the Mg/Ti bimetal joint with the optimized lattice structure is 77.3 MPa. Experimental and simulated results show that the failure strength increases first and then decreases with the increase of l/d, and it reaches the peak value when l/d is 3.

应用于镁/钛双金属复合材料界面强化的添加剂制造钛基金字塔晶格结构的优化

通过超声波辅助固液复合铸造法制造了镁/钛双金属复合材料，其界面具有添加剂制造的钛基金字塔晶格结构。采用田口方法对晶格参数进行了优化。优化后的几何参数包括：支柱直径（d）为 1 毫米，支柱长度与直径之比（l/d）为 3，上下节点与直径之比（d1/d 和 d2/d）分别为 2.5 和 2.5。支柱长度与直径之比是影响破坏强度的最重要因素。采用优化晶格结构的镁/钛双金属接头的破坏强度为 77.3 兆帕。实验和模拟结果表明，随着 l/d 的增大，破坏强度先增大后减小，当 l/d 为 3 时达到峰值。
