摘要:
Ti or a high-Ti alloy is melted in a container composed of high-purity CaO materials on its inner sides. The materials are composed of not less than 99% by weight of CaO, not more than 0.1% by weight of SiO.sub.2, not more than 0.02% by weight of Fe.sub.2 O.sub.3, and not more than 0.5% by weight in total of other metal oxides under a non-oxidizing atmosphere.CaO refractories for use in the melting of Ti or a high-Ti alloy contains not less than 99% by weight of CaO, not more than 0.1% by weight of SiO.sub.2, 0.02% by weight of Fe.sub.2 O.sub.3, and not more than 0.5% by weight of other metal oxides.

摘要:
COMPOSITES OF TITANIUM AND BERYLLIUM ARE FORMED WHICH HAVE A HIGH MODULUS OF ELASTICITY, LOW DENSITY AND USEFUL DUCTILITY. TITANIUM-BERYLLIUM COMPOSITES IN ACCORDANCE WITH THIS INVENTION COMPRISE FROM 90 TO 40% TITANIUM AND FROM 10 TO 60% BY VOLUME BERYLLIUM. THE COMPOSITES ARE FORMED BY CONSOLIDATION OF IRREGULAR SHAPED PATRICLES OF TITANIUM AND BERYLLIUM UNDER CONDITIONS WHICH PREVENT ALLOYING OR COMPOUNDING OF THE TWO METALS.
摘要:
A bimetallic tube comprising a copper-base alloy and a reactive metal such as titanium, is produced by assembling concentrically a tubular member of each of such materials and interposing a layer of copper, nickel or silver between them, forming a bond between the reactive metal and the copper, nickel or silver and extruding the assembly. The bimetallic tube is useful for heat exchange purposes when corrosive fluids are involved and has better heat transfer properties than an all-reactive metal tube.
摘要:
A method of forming titanium sheets and the like in which a sandwich structure consisting of a titanium sheet is placed in an envelope constructed of mild hot rolled steel, forming the sandwich structure utilizing a stretch forming operation, bracing the sandwich structure insuring that it will retain its shape during a stress-relieving operation, performing the stress relieving operation and removing the shaped titanium sheet from the envelope.
