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.
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.
