Abstract

A Fe-l5 atomic percentage Cu mixture was processed by Mechanical Alloying, in a Spex 8000D, and Dynamically Compacted, in a light gas gun. The MA as-powder product was a supersaturated solid solution with a BCC structure (a=0.28736 nm). Nanometric grain sizes between 6 to 30 nm were obtained. Different impact velocities on precompacted cylindrical specimens were used to obtain bulk specimens. The energy used for compaction was between 6 to 10% of the impact energy. XRD and TEM showed no structural changes after DC. We are proposing a Dynamic Compaction Domain in the shock compaction energy vs. Ρ₀/Rho; plane, were consolidation of nanometric powders can take place.
