IRON-BASED ALLOY POWDER CONTAINING NON-SPHERICAL PARTICLES

The present invention relates in a first aspect to an iron-based alloy powder containing non-spherical particles and at least 40% of the total amount of particles have a non-spherical shape. The alloy mandatorily comprises the elements Fe (iron), Cr (chrome) and Mo (molybdenum). Furthermore, the all...

More Information
Summary:The present invention relates in a first aspect to an iron-based alloy powder containing non-spherical particles and at least 40% of the total amount of particles have a non-spherical shape. The alloy mandatorily comprises the elements Fe (iron), Cr (chrome) and Mo (molybdenum). Furthermore, the alloy may comprise further elements such as C (carbon), Ni (nickel), Nb (niobium) or Si (silicon). The present invention relates, according to a second aspect, to an iron-based alloy powder wherein the alloy comprises the elements Fe, Cr and Mo and the iron-based alloy powder is produced by an ultra-high liquid atomization process comprising at least two stages as defined below.
