Processes for fabricating components to have two or more regions with different grain structures, and components produced by such processes. First and second preforms are fabricated to comprise interface surfaces at which the preforms can be joined together. The first and second preforms are formed of first and second precipitation-strengthened alloys, respectively, and the first alloy differs from the second alloy by having a higher solvus temperature or a higher grain refiner content. The preforms are joined together to form an article comprising first and second portions formed by the first and second preforms, respectively, and corresponding to first and second regions of the component, respectively, and the interface surfaces of the preforms form a joint between the first and second portions of the article. A supersolvus heat treatment is performed on the article so that greater grain growth occurs in the second portion than in the first portion.

Superelastic and/or shape memory nickel-titanium alloys having an increased fatigue life that is superior to known nickel-titanium alloys are disclosed. The nickel-titanium alloys have a minimum fatigue life that may be at least about 10 million strain cycles at a strain greater than about 0.75%. The minimum fatigue life may be due, at least in part, to the nickel-titanium alloy having at least one of an oxygen concentration of less than about 200 ppm, a carbon concentration of less than about 200 ppm, the absence of oxide-based and/or carbide-based inclusions having a size greater than about 5 microns (μm), the presence of an R-phase, or combinations of the foregoing. Articles manufactured from such fatigue-resistant nickel-titanium alloys can be more durable because they are more resistant to repetitive strain and crack propagation.

The present invention relates to a means to protect gas turbine components against corrosion from a gaseous stream, produced from an oxidation reaction the reaction being conducted in a continuous oxidation reactor 1. A composition for protecting gas turbine components against corrosion from a paraxylene oxidation off-gas stream comprising nickel- and cobalt-based superalloys. This invention relates to gas turbine components for reduced corrosion when in contact with off gas from paraxylene oxidation. Specifically, the invention relates to gas turbine components constructed of nickel and cobalt based super alloys with aluminide and MCrAlY coatings.The production of terephthalic acid (TA) typically involves the liquid phase oxidation of para-xylene (PX) feedstock using molecular oxygen in acetic acid as a process solvent, in the presence of a dissolved heavy metal catalyst system usually incorporating a promoter, such as bromine as disclosed in U.S. Pat. No. 2,833,816. In general, acetic acid, molecular oxygen in the form of air, para-xylene and catalyst are fed continuously into the oxidation reactor at elevated temperature and pressure, typically a temperature from about 150° C. to about 250° C. and a pressure from about 100 kPa to about 5000 kPa.Para-xylene oxidation produces a high-pressure gaseous stream (or “off-gas”) which comprises nitrogen, unreacted oxygen, carbon dioxide, carbon monoxide and, where bromine is used as a promoter, methyl bromide. In addition, because the reaction is exothermic, the acetic acid solvent is frequently allowed to vaporize to control the reaction temperature and is removed in the gaseous stream. This vapour is typically condensed and most of the condensate is refluxed to the reactor, with some condensate being withdrawn to control reactor water concentration. The portion of the gaseous stream which is not condensed is either vented or passed through a catalytic combustion unit (CCU) to form an environmentally acceptable effluent, ...

METHOD OF ALLOYING REACTIVE COMPONENTS

Номер: US20140076465A1
Принадлежит: Ormco Corporation

Metal ingots for forming single-crystal shape-memory alloys (SMAs) may be fabricated with high reliability and control by alloying thin layers of material together. In this method, a reactive layer (e.g., aluminum) is provided in thin flat layers between layers of other materials (e.g., copper and layers of nickel). When the stacked layers are vacuum heated in a crucible to the melting temperature of the reactive layer, it becomes reactive and chemically bonds to the other layers, and may form eutectics that, as the temperature is further increased, melt homogeneously and congruently at temperatures below the melting temperatures of copper and nickel. Oxidation and evaporation are greatly reduced compared to other methods of alloying, and loss of material from turbulence is minimized. 1. A method of making a hyperelastic single-crystal CuAlNi shape memory alloy , the method comprising: layering a layer of aluminum adjacent to a layer of copper and a layer of nickel;', 'heating the layers;', 'melting the layers;', 'mixing the melted layers; and', 'cooling the mixture to form the ingot;, 'forming an ingot of CuAlNi byplacing a seed of a desired composition for the shape memory alloy into a melt of the ingot;drawing the seed from the melt at a controlled rate so that a solid crystal is formed at a crystallization front; andquenching the drawn crystal to produce a single crystal beta phase.2.
