Abstract: A method of welding articles formed of single-crystal superalloys, particularly single-crystal nickel-base superalloys containing 10 weight percent or more of refractory metals, and welded assemblies formed thereby. A shim is positioned between the articles, and a backing strip is preferably positioned to contact both articles and bridge the gap between the articles. The articles are then welded together using a high energy beam with a low current pulse frequency and low travel speed.

Abstract: Pre-straining and thermal recrystallization processes for maximizing formability in SPF sheet alloys of aluminum, magnesium, iron and titanium can be modified to form sheet products with roughened or textured surfaces for low-slip applications or coating adherence or decorative applications. By determination of suitable pre-strain levels and recrystallization/forming temperatures for s sheet metal stock, relatively large grained microstructures are formed in the sheet that yield useful surface texture during forming.

Abstract: In order to provide an austenitic single crystal stainless steel having preferable stress corrosion cracking resistance, strength, and irradiation induced embrittlement resistance so as to extend the life of a nuclear reactor core structure, which is used under a high radiation dose environment, a method is employed, which comprises the steps of homogeneously dispersing carbides into a parent phase of the austenitic single crystal stainless steel by a two step solution heat treatment, and subsequently effecting an ageing heat treatment after rapid cooling for precipitating fine carbides. Austenitic single crystal stainless steel having preferable stress corrosion cracking resistance, strength, and irradiation induced embrittlement resistance can be provided, and the life of nuclear reactor core structure, which is used under a high radiation dose environment, can be extended.

Abstract: Unwanted recrystallization during heat treatment of a directionally solidified nickel alloy single crystal casting is prevented by chemical milling the part before heat treatment. Removal of a layer of as little as 0.013-0.050 mm thick, less than two percent of the part thickness, has been found effective.
