  • Patent number: 10435775
    Abstract: Methods of refining the grain size of titanium and titanium alloys include multiple upset and draw forging. Titanium and titanium alloy workpieces are heated to a workpiece forging temperature within a workpiece forging temperature range in the alpha+beta phase field. The workpiece may comprise a starting cross-sectional dimension. The workpiece is upset forged in the workpiece forging temperature range. After upsetting, the workpiece is multiple pass draw forged in the workpiece forging temperature range. Multiple pass draw forging may comprise incrementally rotating the workpiece in a rotational direction followed by draw forging the workpiece after each incremental rotation. Incrementally rotating and draw forging the workpiece is repeated until the workpiece comprises substantially the same starting cross-sectional dimension.

  • Patent number: 10407745
    Abstract: A method of producing an article selected from a titanium article and a titanium alloy article comprises melting feed materials with a source of hydrogen to form a molten heat of titanium or a titanium alloy, and casting at least a portion of the molten heat to form a hydrogenated titanium or titanium alloy ingot. The hydrogenated ingot is deformed at an elevated temperature to form a worked article comprising a cross-sectional area smaller than a cross-sectional area of the hydrogenated ingot. The worked article is dehydrogenated to reduce a hydrogen content of the worked article. In certain non-limiting embodiments of the method, the dehydrogenated article comprises an average ?-phase particle size of less than 10 microns in the longest dimension.

  • Patent number: 8747956
    Abstract: 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.
