Thin film thermite oxidation behavior at variable time scales

摘要

Thin film multilayer thermites were subjected to shock compression to observe their exothermic behavior. To probe these thermites at shorter time scales Al/CuO, Zr/CuO, and Mg/CuO thin films were impacted by laser driven flyer plates to explore the shock behavior of nano-thermite. The thin film samples were impacted with flyer plates with variable speeds (.5 to 4 km/s), and threshold detonation energies were calculated. Investigation into interfacial diffusion was also explored using elements of the classic Kirkendall effect.
