| Abstract Scope |
Two-dimensional transition metal carbides, known as MXenes, have wide applications in catalysis, energy storage, and electromagnetic shielding applications due to their interior transition metal carbide core and abundant hydrophilic surface groups. These key features of MXenes also make them useful candidates for tunable solution-based self-assembly processes to form lightweight metal matrix composites. In this talk, we present the tunable self-assembly process of single-to-few layer ~1 nm sheets of Ti3C2Tx MXene to micron-sized Al flakes that can be scaled for industry-scale powder beds. We also illustrate Ti3C2Tx’s mechanical reinforcement and morphological behavior during sintering using in-situ x-ray diffraction (XRD) with samples as low as 1 wt% Ti3C2Tx in Al. We also discuss the Vickers hardness properties and pre- and post-annealing morphology using scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) methods. This talk aims to lay the foundation for future development of lightweight MXene-metal matrix composites for additive manufacturing applications. |
