20080202650 | Heat Treatment Method For Monocrystalline or Directionally Solidified Structural Components - The invention relates to a heat treatment method for monocrystalline or directionally solidified structural components. Said method comprises a heat treatment which results in dissolving at least one crystalline phase of the material of the structural component, referred to in the following as component material. The inventive method is characterized by carrying out the heat treatment by heating the structural component to a dissolution temperature required for dissolving the crystalline phase only in at least one first component area in which the stresses within the component material do not exceed a predetermined value. In at least one second component area in which the stresses within the component material exceed the predetermined value the material is only heated to a temperature below the dissolution temperature. | 08-28-2008 |
20090139613 | HYPERELASTIC SHAPE SETTING DEVICES AND FABRICATION METHODS - Shape-setting methods for fabricating devices made of single crystal shape memory alloys. The method include drawing a single crystal of a shape memory alloy from a melt of the alloy. This is followed by heating and quenching the crystal sufficiently rapid to limit the formation of alloy precipitates to an amount which retains hyperelastic composition and properties of the crystal. | 06-04-2009 |
20100108206 | Preferential hardening of single crystal blades - A method for improving the strength, creep and failure resistance of a single crystal component, such as a turbine engine component, is provided. The method comprises the steps of forming a component, such as a turbine engine component, having a single crystal microstructure with a plurality of γ′ cuboids forming a limited amount of oriented platens in a particular direction prior to the component being placed into service to delay coalescence of the platens relative to the applied load. | 05-06-2010 |
20130042948 | Decorative Steel Composition Having a Textured Cyrstalline Surface - A decorative steel article having a textured crystalline surface includes a steel alloy, single crystal or large, macroscopic grained crystal body. The steel alloy includes iron and at least one element selected from the group of nickel and chromium. The steel article has a surface characterized by a decorative, macroscopic, martensitic phase surface feature. The decorative steel article is suitable for sundry applications where an enhanced visual appearance is desirable. | 02-21-2013 |
20140209219 | SHAPE SETTING A SHAPE MEMORY ALLOY DENTAL ARCH - Methods are provided for shape-setting hyperelastic, single-crystal shape memory alloy (SMA) material while preserving the hyperelastic properties of the material. A wire or rod of a single crystal shape memory alloy material is heated to an annealing temperature (T | 07-31-2014 |
20220136134 | METHOD FOR CLONAL-GROWTH OF SINGLE-CRYSTAL METAL - A method for clonal-growth of a single-crystal metal, including: using copper as an example, placing an existing small-sized single-crystal copper foil with a plane of any index on a copper foil that needs to be single-crystallized, and performing annealing to obtain, by cloning, a large-area (in meters) single-crystal copper foil with the same surface index as that of the parent facet. The method solves the difficult problem of large-area single-crystal copper foil preparation. By performing annealing, a parent single-crystal copper foil with a very small size (˜0.25 cm | 05-05-2022 |
