摘要： One non-limiting embodiment of an apparatus for forming an alloy powder or preform includes a melting assembly, an atomizing assembly, and a collector. The melting assembly produces at least one of a stream of a molten alloy and a series of droplets of a molten alloy, and may be substantially free from ceramic in regions contacted by the molten alloy. The atomizing assembly generates electrons and impinges the electrons on molten alloy from the melting assembly, thereby producing molten alloy particles.

摘要： Processes, systems, and apparatuses are disclosed for forming products from atomized metals and alloys. A stream of molten alloy and/or a series of droplets of molten alloy are produced. The molten alloy is atomized to produce electrically-charged particles of the molten alloy by impinging electrons on the stream of molten alloy and/or the series of droplets of molten alloy. The electrically-charged molten alloy particles are accelerated with at least one of an electrostatic field and an electromagnetic field. The accelerating molten alloy particles are cooled to a temperature that is less than a solidus temperature of the molten alloy particles so that the molten alloy particles solidify while accelerating. The solid alloy particles are impacted onto a substrate and the impacting particles deform and metallurgically bond to the substrate to produce a solid alloy preform.

摘要： Methods of refining the grain size of titanium and titanium alloys include thermally managed high strain rate multi-axis forging. A high strain rate adiabatically heats an internal region of the workpiece during forging, and a thermal management system is used to heat an external surface region to the workpiece forging temperature, while the internal region is allowed to cool to the workpiece forging temperature. A further method includes multiple upset and draw forging titanium or a titanium alloy using a strain rate less than is used in conventional open die forging of titanium and titanium alloys. Incremental workpiece rotation and draw forging causes severe plastic deformation and grain refinement in the titanium or titanium alloy forging.
