Powder-Based Work at Edwards AFB
Abstract
Areas of interest are bulk nanophase aluminum parts for aerospace and astronautics applications and metallic coatings for microtubecomponents. Nanocrystalline materials are defined as polycrystalline materials with crystallites that have manometer rather than micron dimensions. In contrast to conventional course-grained materials, the number of atoms in the grain boundaries can equal or exceed those in the crystal lattice sites. They are materials with superior properties which include: increased strength (for aluminum it increases from 29 ksi to 115 ksi) while maintaining ductility (5%).
