摘要： A non-limiting embodiment of a titanium alloy comprises, in weight percentages based on total alloy weight: 2.0 to 5.0 aluminum; 3.0 to 8.0 tin; 1.0 to 5.0 zirconium; 0 to a total of 16.0 of one or more elements selected from the group consisting of oxygen, vanadium, molybdenum, niobium, chromium, iron, copper, nitrogen, and carbon; titanium; and impurities. A non-limiting embodiment of the titanium alloy comprises an intentional addition of tin and zirconium in conjunction with certain other alloying additions such as aluminum, oxygen, vanadium, molybdenum, niobium, and iron, to stabilize the α phase and increase the volume fraction of the α phase without the risk of forming embrittling phases, which was observed to increase room temperature tensile strength while maintaining ductility.

摘要： A method of producing a metallic powder material comprises supplying feed materials to a melting hearth, and melting the feed materials on the melting hearth with a first heat source to provide a molten material having a desired chemical composition. At least a portion of the molten material is passed from the melting hearth either directly or indirectly to an atomizing hearth, where it is heated using a second heat source. At least a portion of the molten material from the atomizing hearth is passed in a molten state to an atomizing apparatus, which forms a droplet spray from the molten material. At least a portion of the droplet spray is solidified to provide a metallic powder material.

摘要： A system and method for continuous casting. The system includes a melt chamber, a withdrawal chamber, and a secondary chamber therebetween. The melt chamber can maintain a melting pressure and the withdrawal chamber can attain atmospheric pressure. The secondary chamber can include regions that can be adjusted to different pressures. During continuous casting operations, the first region adjacent to the melt chamber can be adjusted to a pressure that is at least slightly greater than the melting pressure; the pressure in subsequent regions can be sequentially decreased and then sequentially increased. The pressure in the final region can be at least slightly greater than atmospheric pressure. The differential pressures can form a dynamic airlock between the melt chamber and the withdrawal chamber, which can prevent infiltration of the melt chamber by non-inert gas in the atmosphere, and thus can prevent contamination of reactive materials in the melt chamber.
