摘要： A non-limiting embodiment of a titanium alloy comprises, in percent by weight based on total alloy weight: 5.1 to 6.5 aluminum; 1.9 to 3.2 tin; 1.8 to 3.1 zirconium; 3.3 to 5.5 molybdenum; 3.3 to 5.2 chromium; 0.08 to 0.15 oxygen; 0.03 to 0.20 silicon; 0 to 0.30 iron; titanium; and impurities. A non-limiting embodiment of the titanium alloy comprises an intentional addition of silicon in conjunction with certain other alloying additions to achieve an aluminum equivalent value of at least 6.9 and a molybdenum equivalent value of 7.4 to 12.8, which was observed to improve tensile strength at high temperatures.

摘要： A method of processing a metal alloy includes heating to a temperature in a working temperature range from a recrystallization temperature of the metal alloy to a temperature less than an incipient melting temperature of the metal alloy, and working the alloy. At least a surface region is heated to a temperature in the working temperature range. The surface region is maintained within the working temperature range for a period of time to recrystallize the surface region of the metal alloy, and the alloy is cooled so as to minimize grain growth. In embodiments including superaustenitic and austenitic stainless steel alloys, process temperatures and times are selected to avoid precipitation of deleterious intermetallic sigma-phase. A hot worked superaustenitic stainless steel alloy having equiaxed grains throughout the alloy is also disclosed.

摘要： Processes and methods related to processing and hot working alloy ingots are disclosed. A metallic material layer is deposited onto at least a region of a surface of an alloy ingot before hot working the alloy ingot. The processes and methods are characterized by a reduction in the incidence of surface cracking of the alloy ingot during hot working.

摘要： A method for heat treating a powder metallurgy nickel-base alloy article comprises placing the article in a furnace at a start temperature in the furnace that is 80° C. to 200° C. below a gamma prime solvus temperature, and increasing the temperature in the furnace to a solution temperature at a ramp rate in the range of 30° C. per hour to 70° C. per hour. The article is solution treated for a predetermined time, and cooled to ambient temperature.

摘要： An apparatus for casting metals by a nucleated casting technique to create a preform, the apparatus including a mold having a base and a side wall where the base can be moved relative to the side wall to withdraw the preform as it is being created. In various circumstances, portions of a droplet spray created by an atomizing nozzle, i.e., overspray, may accumulate on a top surface of the side wall and prevent or inhibit the preform from being moved relative to the side wall. The atomizing nozzle can be oriented such that the droplet spray passes over the top of the side wall to remelt and remove at least a portion of the overspray that has accumulated thereon. The mold can be rotated such that the overspray formed on a region of or on the entire perimeter of the top surface can pass through the droplet spray and can be removed from the side wall.

摘要： 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 α-phase particle size of less than 10 microns in the longest dimension.
