WEAR RESISTANT ALLOY

Japanese Patent JP2020143380

A

To provide a powder metallurgy produced alloy having an improved property profile for advanced forming applications, or to provide a powder metallurgy produced alloy having a composition and microstructure leading to improvements in the surface quality of products produced by the use of the alloy in tools and molds.SOLUTION: There is provided an alloy produced by powder metallurgy and having a non-amorphous matrix. The alloy consists of C 0-2.5 wt.%, Si 0-2.5 wt.%, Mn 0-15 wt.%, Cr 0-25 wt.%, Mo 4-35 wt.%, B 0.2-2.8 wt.%, optional elements, balance Fe and/or Ni apart from impurities. The alloy comprises 3-35 volume % hard phase particles, wherein the hard phase particles comprise at least one of borides, nitrides, carbides and/or combinations thereof, at least 90% of the hard phase particles have a size of less than 5 μm and at least 50% of the hard phase particles have a size in the range of 0.3-3 μm.SELECTED DRAWING: Figure 1
