| Abstract Scope |
Through an integrated computational and experimental research partnership, we investigate the activation and confinement of deformation mechanisms directly linked to the hierarchical structure at the nanoscale in multilayered nanocomposite materials, to potentially enable tunable strength and toughness. We utilize a metal/MAX multilayered nanolaminate (MMN) system where the interfaces between the metallic and MAX phase layers are in direct competition with the interfaces within the MAX layers for deformation. By leveraging the competition between operative deformation mechanisms within the MMN we seek to control the activation barrier for MAX phase deformation. We discuss the challenges experimentally and computationally associated with synthesizing, modeling, and simulating MMN systems and share some of the insights we gained on these engineered interface nanolaminate systems. We highlight the impressive accuracy of our MAX phase interatomic potential to model the deformation behavior and share the first successful deposition of a Ti/ Tin+1AlCn and its mechanical properties. |
