The operating conditions of modern materials and devices are progressing towards more extreme aerodynamic, mechanical, radiation, and corrosive environments. These conditions narrow material selection to a small subset, necessitating the development for next-generation material solutions with highly tailored structures. These materials are defined as architectured because they exploit specific design of microstructure (e.g., homo/hetero interfaces), meso-structure (e.g., 3D topologies), phase-structure (e.g., laminated composites), and combinations thereof. With recent advances in fabrication techniques, it is now possible to improve material performance by controlling architectures across nano- and micro-meter length scales. However, the service lifetimes of these materials are often unknown or fall short when compared to industry standards.

The ultimate implementation of architectured materials requires a mechanistic understanding of how they behave and evolve when subjected to extreme environments. This symposium will bring together different communities to identify key mechanisms to understand and predict how materials behave when subjected to a diversity of extreme conditions. Symposium contributions should address basic science regarding the performance, stability, and evolution of emerging architectured materials in extreme environments. Discussion of material design principles, fabrication techniques, and novel testing methods are also welcomed.
