Abstract: Small amounts of rare earth elements are added to an .alpha. or near-.alpha. alloy of titanium and IIIA, IVA metals to provide a rare earth/IIIA, IVA metal precipitate during an age hardening heat treatment after rapid solidification of the alloy. Age hardening of the rapidly solidified alloy of .alpha. or near .alpha.-titanium creates a fine, uniform, equidistant, high density, spherical 50-100 Angstrom precipitate of the resulting rare earth/IIIA, IVA metal compound to produce a precipitate-hardened allow with twice the strength of the alloy without rare earth additives. The precipitate hardening which predominates the other hardening processes occurs during the heat treating step after rapid solidification, with the quenching associated with the rapid solidification producing solid solution hardening.

Abstract: The microstructure of titanium is refined by inducing a high temperature transformation from .alpha.+.beta. to .beta. and back to .alpha.+.beta. by diffusing hydrogen into and then out of the metal while maintaining the metal above the temperature of hydride formation. The titanium is heated to a temperature just below the .alpha.+.beta. to .beta. transformation temperature, and hydrogen is diffused into the metal thereby inducing the phase change. The hydrogen is diffused out of the metal again inducing a phase change. When the hydrogen has been removed, the metal is allowed to cool to room temperature.

Abstract: Titanium alloy composites having substantially reduced reaction zones are provided which comprise a high strength/high stiffness filament such as silicon carbide, silicon carbide-coated boron, boron carbide-coated boron and silicon-coated silicon carbide, embedded in a fine-grained titanium alloy containing at least 40 percent beta phase, less than 7 percent Al and having a beta-transus temperature below 1750.degree. F. (955.degree.

Abstract: A non-alloy steel component is nitrocarburized at 550.degree. to 720.degree. C. for up to 4 hours in a nitriding gaseous atmosphere eg. ammonia or ammonia and endothermic or exothermic gas, and is thus exposed to air or other oxidizing atmosphere for 2 to 120 seconds to form an oxide-rich layer thereon before being quenched into an oil/water emulsion, degreased and a tack-free wax coating applied. Alternatively, the component may be cooled in air or other oxidizing atmosphere and then wax coated or it may be cooled in a non-oxidizing atmosphere and then reheated to provide the oxide-rich surface layer before being cooled again and wax coated. As a further alternative, the component may be cooled, lapped to a surface roughness of not more than 0.2 micrometers Ra, reheated to oxidize and then quenched. These techniques give a good corrosion resistance to the component.

Abstract: The present invention belongs to a technical field of cold rolled steel sheet. The present invention provides a thin steel sheet suitable to be formed into, for example, an external automotive plate by a method including an appearance-finishing step by bake coating as a final step after drawing (such as press molding). The present invention aims to improve remarkably the yield strength, so-called bake hardenability, of the thin steel sheet in order to produce advantageously a light weight automobile. In addition, the invention aims to compensate advantageously the deterioration of dent resistance of the automobile due to the lowering of the weight, without deteriorating the r value, which is an indication of the press moldability of the thin steel sheet. Accordingly, the present invention discloses an effective compounding amount of Nb, which acts to fix C and N in the steel in the presence of a proper amount of Al, and an annealing condition capable of developing effectively the contribution of Nb.

F. for 1/4-4 hours and a final (lower intensity) shot peening.A relatively homogeneous surface of aged martensite is produced and selective attack which forms sharp pit-like defects which initiate cracks is avoided.
