Beschreibung
Zusammenfassung:	The invention relates to various methods for modifying material properties during solid-state impact consolidation of coatings and free-form fabrication of structures. The invention discloses a new method for modifying the physical and chemical properties of the substrate, coating, and free-form structure during and simultaneous to impact consolidation and accretion of powders using a solid-state deposition process. The physical and chemical properties of the substrate, coating, and free-form structure in close proximity to the impact consolidation process can be modified by heating or by exposing to gaseous and liquid environments. Heating of the substrate, coating, or free-form structure up to annealing temperatures for most materials significantly reduces the plastic deformation flow stresses and permits the impact consolidation process to enhance deposition efficiency, improve densification, anneal dislocations, and improve adhesion and cohesion through in-situ diffusion bonding.
