Definitions

  • the present invention also provides a method of manufacturing the components from the hard metal materials.
  • insoluble is understood herein to mean that for all intents and purposes the refractory material is not soluble in the host metal. There may be limited solubility. However, the refractory particles are essentially distinct from the host metal in that there is negligible partitioning of the transition metals in the refractory material particles to the host metal.
  • the refractory material may be less than 200 microns particle size .
  • the refractory material may be added to the host liquid metal as follows .
  • (a) As a fine powder with a selected particle size distribution. For example, 15 wt.% of particles of a refractory material in the form of niobium carbide (NbC) (minus 50 microns in diameter) added to a liquid host metal in the form of a high chromium white cast iron host metal. NbC exhibits a Vickers Hardness of 24 GPa, a melting point of 3600°C, and a very low solubility in the host liquid metal at a casting temperature of about 1500°C.
  • the liquid metal slurry comprises a suspension of insoluble NbC particles
  • refractory material particles that firmly held the particles in the host metals on solidification. All refractory particles in hard metal material castings produced by the applicant in an inert atmosphere were found to be under compressive loading ensuring intimate contact and good bonding with the host metals. Density of refractory materials
  • solubility in the host liquid metal to produce a casting in accordance with the method of the present invention, produces a hard metal material that displays physical and chemical properties that are very similar to the host metal with substantially

  • the method may comprise adding the niobium to the melt in the form of ferro-niobium, for example particles of ferro- niobium.
  • ferro-niobium dissolves in the melt and the resultant free niobium and carbon in the melt form niobium carbides in the melt.
  • the method may also comprise adding the niobium to the melt as elemental niobium.
  • the method may also comprise adding the niobium and the titanium to the melt as ferro-niobium-titanium.
  • the method may also comprise adding the niobium to the melt in the form of particles of niobium carbide.
  • the method may also comprise
  • the niobium and/or the titanium may be added to the melt to produce particles of niobium carbide and/or niobium/titanium carbides in a range of 12 wt% to 33 wt% niobium carbides and niobium/titanium carbides of the total weight of the solidified hard metal material .
  • the niobium and/or the titanium may be added to the melt to produce particles of niobium carbide and/or niobium/titanium carbides in a range of 12 wt% to 25 wt% niobium carbides and niobium/titanium carbides of the total weight of the solidified hard metal material .
  • the method may comprise adding particles of niobium carbide and/or particles of niobium/titanium carbides to the melt under inert conditions, such as an argon blanket, to reduce the extent to which niobium carbide and/or titanium carbide oxidize while being added to the melt.
  • inert conditions such as an argon blanket
  • the method may comprise pre-melting ferro-niobium and ferro-titanium and/or ferro-niobium-titanium under inert conditions and forming a liquid phase that is a homogeneous chemical mixture of iron, niobium and titanium and solidifying this chemical mixture.

  • High chromium white cast iron alloys conventionally rely on the high chromium content to produce a significant volume of hard chromium carbides that provide castings with high wear resistance.
  • high chromium white cast iron alloys conventionally rely on some chromium remaining in the ferrous matrix and provides alloys with corrosion resistance.
  • the density of NbC is 7.8 grams/cc at room temperature and this is close to the density of high chromium white cast iron (7.5
  • the density of TiC is 4.9 grams/cc at room temperature, and this is much less than the density of NbC. Since TiC and NbC are isomorphous, it is possible to achieve any density value for the mixed carbide in a range 4.9-7.8 grams/cc by selecting the corresponding chemical composition with the general formula
