    摘要: A powder metallurgy corrosion and wear resistant tool steel article, and alloy thereof. The article is manufactured by hot isostatic compaction of nitrogen atomized, prealloyed high-chromium, high-vanadium, high-niobium powder particles. The alloy is characterized by very high wear and corrosion resistance, making it particularly useful for use in the manufacture of components for advanced bearing designs as well as machinery parts exposed to severe abrasive wear and corrosion conditions, as encountered, for example, in the plastic injection molding industry and food industry.

    摘要: A powder metallurgy cold-work tool steel article of hot isostatic compacted nitrogen atomized, prealloyed powder. The alloy of the article includes the addition of niobium, which combined with the use of gas atomization, results in a fine carbide size distribution. This in turn results in improved bend fracture strength and impact toughness. In addition, as a result of isostatic compaction of nitrogen gas atomized prealloyed powder a fine distribution of carbides results to obtain a microstructure that achieves both improved toughness and wear resistance.

    摘要: Nickel base alloys for use in applications for highly corrosive and abrasive environments. The alloys contain a large volume fraction of metallic carbide particles that provide wear and abrasion resistance. The alloys are produced by induction melting and gas atomization to form alloy powder particles. The particles are consolidated by hot isostatic pressing to form a solid article.

    摘要: A fully dense, powder-metallurgy produced maraging steel alloy article of prealloyed powder for use as a tool for high temperature applications. The article in the as-produced condition having a hardness less than 40 HRC to provide machinability and thereafter the article upon maraging heat treatment having a hardness greater than 45 HRC. A method for producing this article comprises compacting prealloyed powder to produce a fully dense article having a hardness less than 40 HRC and thereafter maraging heat treating to a hardness greater than 45 HRC.

    摘要: A method for producing an autogenous welded tubular metal article having a substantially uniform grain size, including the weld-affected area thereof. This is achieved by applying to the metal article a series of cold reduction and annealing operations that in combination render the grain size of the weld-affected area uniform with respect to the remainder of the cross-section of the article, and particular the visual appearance of the cross-section.
