A method of manufacturing a ferrous alloy article is disclosed and includes the steps of melting a ferrous alloy composition into a liquid, atomizing and solidifying of the liquid into powder particles, outgassing to remove oxygen from the surface of the powder particles, and consolidating the powder particles into a monolithic article.

Method of manufacturing a ferrous alloy article using powder metallurgy processing

A corrosion resistant, neutron absorbing, austenitic alloy powder is disclosed having the following composition in weight percent.  The alloy contains at least about 0.25% B, at least about 0.05% Gd, and the balance of the alloy composition is iron and usual impurities. Bis defined as % B+4.35&#xd7;(% Gd). An article of manufacture made from consolidated alloy powder is also disclosed which is characterized by a plurality of boride and gadolinide particles dispersed within a matrix. The boride and gadolinide particles are predominantly MB, MB, MX, and MX in form, where X is gadolinium or a combination of gadolinium and boron and M is one or more of the elements silicon, chromium, nickel, molybdenum, iron.

High strength, high fracture toughness alloy

An improved hot work tool steel has higher hardness capability and better temper resistance above 1100 F. and better wear resistance than AISI type H13 and better toughness and ductility then AISI type H10 or type H21. The steel alloy contains essentially the following in weight percent:

Hot work tool steel with good temper resistance

A low cobalt maraging steel has a yield strength of at least about 240 ksi (about 1655 MPa) in the aged condition in combination with good toughness as indicated by a longitudinal Charpy V-notch impact toughness of at least aobut 20 ft-lb (about 27 J), as well as good notch ductility. The alloy contains, in weight percent, about:
