This method comprises selecting a carburizing grade material to form an article, carburizing the article to form a microstructure on at least one portion of the article having a predetermined density of carbides dispersed in the microstructure to a predetermined depth, quenching the article to form a hardened matrix dispersed with carbides and hard finishing the article to form the surface, the surface having at least approximately 20% by volume fraction carbides dispersed in the hardened matrix.

Abstract: A Gram-negative bacterium useful for genetically engineering plants is provided. The Gram-negative bacterium contains, as part of genome, an inducible regulatory sequence operatively linked to a nucleotide sequence encoding a levansucrase. Alternatively, the Gram-negative bacterium comprises a recombinant nucleic acid construct containing an inducible regulatory sequence operatively linked to a nucleotide sequence encoding a levansucrase. Also provided are recombinant nucleic acid constructs comprising an inducible regulatory sequence operatively coupled to a nucleotide sequence encoding a levansucrase and a method for transforming plants using the Gram-negative bacterium of the present invention.

Abstract: A method is provided for gene suppression in eukaryotes by transformation with a recombinant construct containing a promoter, at least one antisense and/or sense nucleotide sequence for the gene(s) to be suppressed, wherein the nucleus-to-cytoplasm transport of the transcription products of the construct is inhibited. In one embodiment, nucleus-to-cytoplasm transport is inhibited by the absence of a normal 3′ UTR. The construct can optionally include at least one self-cleaving ribozyme. The construct can also optionally include sense and/or antisense sequences to multiple genes that are to be simultaneously down-regulated using a single promoter. Also disclosed are vectors, plants, animals, seeds, gametes, and embryos containing the recombinant constructs.

Abstract: A method and apparatus for characterizing a quench for producing desired hardness characteristics on a steel part. The characterization preferably includes a series of heat transfer coefficients versus temperature for the quench determined from information representative of known quenches and distinguishing part characteristics such as geometry, size and composition. The quench characterization determined using the present method and apparatus can be utilized in hardness prediction software programs, and for determining a suitable quench for producing the desired hardness characteristics on the part.

Abstract: A process for improving fatigue resistance of a case hardened component having a case thickness "t", subjected to one or more of rolling, sliding, abrasion, bending and pitting includes determining the magnitude of fatigue strength at surface and at a plurality of pre-selected points along thickness "t" of a component. The applied fatigue stresses acting upon the component at the surface and at the plurality of pre-selected points along thickness "t" are also determined. Then, a compressive residual stress profile is tailored from the surface to thickness "t" of the component. The compressive residual stresses at the surface and at the plurality of the pre-selected points along thickness "t" respectively have a magnitude sufficient to attain a net resultant stress which is at least 25% lower than the fatigue strength at the surface and the corresponding plurality of pre-selected points.

Abstract: A crankshaft is manufactured by providing a plurality of initially completely discrete crankshaft segments electron-beam welded together. Tubular bearing journals (12,14) having an inclined surface (30) are positioned in a groove (35,40) of a counterweight web (16) and a groove (50) of a crankshaft end (18). The discrete segments (12,14,16,18) are positioned and maintained in position by the interaction of inclined surfaces (30) and grooves (35,40,50) for electron-beam welding.
