Abstract: 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.

Abstract: A nickel based single crystal superalloy comprising 7-9 wt % cobalt, 3.5-4.5 wt % chromium, 0-2.4 wt % molybdenum, 4-8 wt % tungsten, 3.5-6 wt % rhenium, 5-6.5 wt % aluminium, 6.5-8.5 wt % tantalum, 0-0.2 wt % hafnium and the balance nickel plus incidental impurities. The nickel based single crystal superalloy is suitable for use as a gas turbine engine turbine blade or turbine vane. It is of particular us on cooled turbine blades and turbine vanes which have ceramic thermal barrier coatings, because the superalloy is compatible with the ceramic thermal barrier coating to minimise spalling. The superalloy has better mechanical properties than other second-generation single crystal superalloys and has better creep strength and oxidation resistance.

Abstract: A method of welding articles (12,14) formed of single-crystal superalloys, particularly single-crystal nickel-base superalloys containing 10 weight percent or more of refractory metals. A shim (24) is positioned between the articles (12,14), and a backing strip (16) is preferably positioned to contact both articles (12,14) and bridge the gap between the articles (12,14). The articles (12,14) are then welded together using a high energy beam (38) with a low current pulse frequency, i.e. about 10 to 50Hz, and low travel speed, i.e. about 0.85 to about 1.5cm/s.

Abstract: A process for the production of an electrical steel sheet having the ideal (100) [001] cube texture of iron or iron alloy, comprising cold rolling a sheet of a single crystal or large grained crystals of iron or iron alloy, in which said single crystal is or a majority of said large grained crystals are oriented so that the pole of the {114} plane may form an angle not greater than 15° with the normal direction of the plane of the sheet, and the direction may form an angle not greater than 15° with a single direction in the plane of the sheet, in said single direction at a rolling reduction of at least 40%, and annealing the rolled sheet to form a primary recrystallization texture of fine grains of an average grain size of not larger than 5 mm under conditions preventing the occurrence of secondary recrystallization.
