Spray forming commercial products: Principles and practice
Spray forming in the Osprey mode utilizes the sequential steps of atomization and droplet consolidation to produce near-net-shape preforms. The process is described in terms of operational and material parameters, advantages relative to ingot and powder metallurgy, and product forms. A brief overview is given of the models developed to describe the process in order to optimize yield, microstructure and properties, and to control the shape of the product. Metallurgical characteristics and properties are assessed in comparison to counterpart ingot metallurgy alloys. Commercial applications of the process are illustrated; these include the spray forming of billets, rolls, rings and tubing.
