Abstract

In this paper, the in-situ tensile behavior of Ti/Al laminated metal composites (LMCs) prepared via ultrasonic additive manufacturing (UAM) was investigated by optical microscopy combined with digital image correlation. Compared with pure Ti foil and Al/Al LMCs processed via UAM, the Ti/Al LMCs exhibit a significantly larger plasticity with intermediate tensile strength. This can be attributed to (ⅰ) strain dispersion in Ti/Al LMCs, (ⅱ) necking inhibiting due to well-bonded interface during early stage of deformation, and (ⅲ) microcracking during late stage of deformation at the rough Ti/Al interfaces, which originate from direct contact between Ti foil and sonotrode.

通过超声波快速成型技术制造的钛/铝层状金属复合材料拉伸行为的原位研究

本文采用光学显微镜结合数字图像相关技术，研究了通过超声增材制造（UAM）制备的钛/铝层状金属复合材料（LMC）的原位拉伸行为。与纯钛箔和通过 UAM 加工的铝/铝 LMC 相比，钛/铝 LMC 具有明显较大的塑性和中等的抗拉强度。这可归因于(ⅰ) Ti/Al LMC 中的应变分散；(ⅱ) 变形早期由于良好的结合界面而产生的颈缩抑制；以及(ⅲ) 变形晚期在粗糙的 Ti/Al 界面上产生的微裂纹，这些微裂纹源于钛箔与超声电极之间的直接接触。

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
