Abstract: A diffusion-bonded powder having an iron powder having 1-5%, preferably 1.5-4% and most preferably 1.5-3.5% by weight of copper particles diffusion bonded to the surfaces of the iron powder particles. The diffusion bonded powder is suitable for producing components having high sintered density and minimum variation in copper content. The iron powder may be produced by providing an atomized iron powder with an oxygen content of 0.3-1.2% by weight and with a carbon content of 0.1-0.5% by weight, and subjecting the atomized iron powder and a copper containing powder to a reduction annealing process in a reducing atmosphere to obtain the iron based powder.

Abstract: Disclosed is a new diffusion-bonded powder consisting of an iron powder having 1-5%, preferably 1.5-4% and most preferably 1.5-3.5% by weight of copper particles diffusion bonded to the surfaces of the iron powder particles. The new diffusion bonded powder is suitable for producing components having high sintered density and minimum variation in copper content.

Abstract: Particles made from a High Speed Steel (HSS) that is modified to contain dispersed precipitations of manganese sulfide (MHSS), a Powder Metallurgy (PM) method using the same, and a part produced by the PM process using the modified HSS particles. By forming a melt of a HSS and 1) Mn or a Mn-containing compound and 2) S or an S-containing compound, followed by an atomization process, modified HSS particle can be obtained containing dispersed sulfide precipitations containing mainly manganese sulfide. The amount of Mn and S are chosen such that the weight ratio of Mn to S (Mn/S), in wt-% of the total weight of the particle, is in the range of 8.0-1.0. An article obtained by a PM manufacturing method using the particles has improved machinability as compared to a an article prepared from a corresponding non-modified HSS.

Abstract: A material which can be used to manufacture components which exhibit high strength and high wear resistance, at the same time possessing reasonable ductility. The material also has cost advantages compared to other potential metal powder solutions. An iron based powder composition which achieves desired microstructure/properties and associated sliding wear resistance with reduced content of expensive alloying ingredients such as admixed elemental Ni and Copper.

Abstract: A method for producing brazing preforms including the steps of providing an iron-, iron and chromium-, nickel- or cobalt-based spherical brazing powder. Converting the brazing powder into an agglomerated coarser powder suitable to be compacted into desired preforms and ejecting the preforms from the compaction die, the preforms having integrity and strength enough to let them be handled in an automated brazing line. Optionally, after ejecting from the compaction die, the preforms may be heat treated or subjecting to a sintering process if higher strength is desired. Also, the preform per se and a brazing process utilising the brazing preform.
