摘要： A hybrid article is disclosed including a sintered coating disposed on and circumscribing the lateral surface of a core having a core material and a greater density than the sintered coating. The sintered coating includes more than about 95% up to about 99.5% of a first metallic particulate material including a first melting point, and from about 0.5% up to about 5% of a second metallic particulate material having a second melting point lower than the first melting point. A method for forming the hybrid article is disclosed including disposing the core in a die, introducing a slurry having the metallic particulate materials into a gap between the lateral surface and the die, and sintering the slurry. A method for welding a workpiece is disclosed including the hybrid article serving as a weld filler.

摘要： A method of making a small diameter elongated steel article such as wire or strip is disclosed. The method includes the step of melting a steel alloy having the following weight percent composition C0.88-1.00 Mn0.20-0.80 Si0.50max. P0.050max. S0.010-0.100 Cr0.15-0.90 Ni0.10-0.50 Mo0.25max. Cu0.08-0.23 V0.025-0.15  N0.060max. O0.040max. and the balance is iron and usual impurities. The method includes melting the alloy, atomizing the molten alloy to make a pre-alloyed metal powder, consolidating the metal powder to substantially full density, and then hot working the consolidated metal powder to form an intermediate elongated article. The method further includes a multi-step heat treating process. A small diameter, elongated steel article having enhanced machinability is also disclosed.

摘要： In various embodiments, metallic wires are fabricated by combining one or more powders of substantially spherical metal particles with one or more powders of non-spherical particles within one or more optional metallic tubes. The metal elements within the powders (and the one or more tubes, if present) collectively define a high entropy alloy of five or more metallic elements or a multi-principal element alloy of four or more metallic elements.

摘要： A thermal mechanical treatment method includes consolidating a powder by a severe plastic deformation process and ageing the consolidated powder at low temperature. The method may include cryomilling the powder before consolidating the powder by a severe plastic deformation process; hot isostatic pressing the consolidated powder into a dense powder before aging the consolidated powder; hot extruding the dense powder into a stock shape before aging the consolidated powder; hot-working the stock shape on a gyrating forge at a predetermined temperature before aging the consolidated powder; or heating the consolidated powder to a predetermined temperature, and maintaining the consolidated powder at the predetermined temperature for a predetermined time.
