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 silicide-based composite toughened with a niobium-based metallic phase, and further containing a phase that significantly improves the oxidation resistance of the composite. The oxidation-resistant phase is a chromium-based Laves-type phase modified with silicon, which has been shown to greatly increase the oxidation resistance of silicide-based composites at temperatures of up to 1200 C. The oxidation-resistant silicide-based composite generally contains one or more silicide intermetallic phases, each of which is an M.sub.5 Si.sub.3 -type phase where M is Nb+Ti+Hf. The niobium-based metallic phase contains niobium, titanium, hafnium, chromium, aluminum and silicon. The silicon-modified Laves-type phase is of the Cr.sub.2 M type where M is Nb+Ti+Hf. A silicide-based composite contains, in atomic percent, about 12-25% titanium, about 6-12% hafnium, about 15-25% chromium, about 1-8% aluminum and about 12-20% silicon, with the balance essentially niobium.

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.
