摘要： An extension is formed directly on an article by casting a compatible material into a ceramic mold that is attached on an end of the article, followed by cooling of the end under controlled conditions sufficient to cause an integral extension to solidify on the article. A ceramic mold is utilized over the end of the article, with a mold cavity that generally defines the shape of the extension to be formed. The mold may be formed in situ on the mandrel, or preformed and attached to the subject article over the mandrel. Extensions formed by the method of this invention have a microstructure that is continuous and compatible with that of the article. Such microstructures may include epitaxial growth of the extension from the microstructure of the article. The method establishes a temperature gradient within the article during solidification that may be further controlled by auxiliary heating and/or cooling of the article and/or extension during the practice of the method.
摘要翻译：通过将相容的材料浇铸到附着在制品末端上的陶瓷模具中，直接在制品上形成延伸部分，然后在足以使制品上产生整体延伸的固化条件的受控条件下进行冷却。在制品的端部使用陶瓷模具，其中模腔通常限定待形成的延伸部的形状。模具可以在心轴上原位形成，或者通过心轴预成型并附着到主体制品上。通过本发明的方法形成的延伸部具有与制品的连续且兼容的微结构。这种微结构可以包括从制品的微观结构延伸的外延生长。该方法在固化期间在制品内建立温度梯度，其可以在该方法的实践期间通过辅助加热和/或冷却制品和/或延伸来进一步控制。

摘要： Coatings suitable for use as protective oxide-forming coatings on Nb-based substrates exposed to high temperatures and oxidative environments. The coatings contain chromium and/or molybdenum, preferably contains silicon, and optionally contains niobium, titanium, hafnium, iron, rhenium, tantalum, and/or tungsten, which in combination form multiple intermetallic phases, which in combination form one or more intermetallic phases that promote the formation of a slow-growing oxide scale. Depending on the particular coating composition, the intermetallic phases may be: a silicon-modified Cr2Nb Laves phase and optionally a chromium solid solution phase, a CrNbSi intermetallic phase, and/or an M3Si intermetallic phase where M is niobium, titanium, and/or chromium; or M5Si3, MSi2 and/or M3Si2 where M is molybdenum, niobium, titanium, chromium, hafnium, iron, rhenium, tantalum, and/or tungsten.

摘要： A method for forming an article is described. The method includes the step of applying a precursor material to at least one surface of a mold structure for casting the article, and curing the applied precursor material. The precursor material includes facecoat-forming constituents which can be curably converted into a facecoat; and a protective coating-former for the article being cast. Molten material is then introduced into the mold structure, so as to come in contact with the facecoat formed from the cured precursor material. The molten material is cooled, to form the article. The cured precursor material, which is in contact with a surface of the cast article, is then reacted with the article, to form the protective coating on the surface of the article. Related mold structures are also described.

摘要： A rare earth-based core for use in the casting of a reactive metal is described. The core contains a ceramic composition which includes at least about 10% by weight of monoclinic rare earth aluminate (RE4Al2O9), wherein RE represents at least one rare earth element; and at least about 10% by weight of at least one free rare earth oxide. The ceramic phase of the composition may include a microstructure which comprises a multitude of substantially spherical pores which are formed as a result of the removal of aluminum metal from the core composition during a heat treatment step. Additional embodiments relate to a method for the fabrication of a ceramic core, employing a rare earth oxide, aluminum metal, and a binder. Methods for removing cores from a cast part are also described.
