Definitions

  • order of addition of the alloying ingredients may be significant. It is difficult to add the germanium first to a copper alloy and then to add the boron. The problem is that when using copper boride as the source of boron a much higher temperature is required to dissolve the boron into the alloy and the germanium content of the alloy may therefore be put at risk by overheating.
  • the present master alloy is therefore normally made by melting together the highest melting elements first and progressively working through the lower melting temperature elements.
  • boron is added e.g. as a boron hydride or metal boron hydride, which decomposes in contact with the molten metal of the master alloy and disperses boron into the alloy with reduced opportunity for development of hard spots and the like.
  • Addition of small quantities of thermally decomposable boron-containing gas to the inert gas being bubbled through the melt readily provides from a desired few ppm to some hundreds or even thousands of ppm of boron into the molten metal or alloy.
  • the introduction of the boron compound into the copper or copper alloy as a dilute gas stream over an period of time, the carrier gas of the gas stream serving to stir the molten copper or alloy, rather than in one or more relatively large quantities is believed to be favourable from the standpoint of avoiding development in the metal or alloy of boron hard spots, with the result that the resulting boron-containing alloy can serve as a master alloy for precious metal alloy manufacture with reduced development of hard spots.
  • the initial reaction is believed to be decomposition of the boron containing grain refiner.
  • the sodium, hydrogen and boron are all effective to deoxidize the melt as follows: (2) Na(g)+0.5O 2 (g) ⁇ Na 2 O(s) (3) H 2 (g)+0.5O 2 (g) ⁇ H 2 O(g) (4) B(s)+0.5O 2 (g)+0.5H 2 (g) ⁇ HBO(g)
  • the boron may be dispersed throughout the molten metal by stirring for in excess of 1 minute and typically for from 1-5 minutes. Stirring may be by any means which does not contaminate the molten metal such as with a graphite stirring rod.
  • the present master alloys may be used to make alloys of silver.
  • the weight ratio of germanium to incidental ingredient elements may be from 100: 0 to 80: 20, preferably from 100: 0 to 60: 40.
  • incident ingredients permits the ingredient to have ancillary functionality within the alloy e.g. to improve colour or as-moulded appearance, and includes amounts of the metals or metalloids Si, Zn, Sn or In appropriate for "deox".
  • the germanium content of the Ag-Cu-(Zn)-Ge or Ag-Cu-(Si)-Ge alloys should be at least 0.1 wt%, preferably at least 0.5 wt%, more preferably at least 1.1 wt%
  • the germanium content is most preferably not more than 1.5%, by weight of the alloy, more preferably no more than 4 wt% up to a maximum of preferably no more than 6.5 wt%.
  • Silicon in particular, may be added to silver alloys e.g. in an amount of up to 0.5 wt %, typically 0.5-3 wt %, more usually 0.1-0.2 wt%, and is conveniently provided in the form of a copper-silicon master alloy containing e.g. about 10 wt% Si.
  • a silver-copper-germanium ternary alloy it can provide investment castings that appear bright immediately on removal from the mould. It may be added to casting grain e.g. before investment casting or it may be incorporated into the silver at the time of first melting to form an alloy.
  • Particular known silver alloys that may benefit from incorporation of boron as Cu-Ge-B using the master alloys produced by the invention include the following:
  • the crucible is pivoted to permit the molten alloy to be poured into a tundish whose bottom is formed with very fine holes.
  • the molten alloy pours into the tundish and runs through the holes in fine streams which break into fine pellets which fall into a stirred bath of water and become solidified and cooled.
  • the cast pellets are removed from the bath and dried to give a master alloy as casting grain.
  • the above master alloy can be used in the manufacture of Ag-Cu-Ge alloys containing boron as melt refiner e.g. using the procedures of the preceding Examples. Dispersion of boron into the master alloy using the borohydride is very effective, and the resulting silver alloys can contain up to 20 ppm boron, or if desired above 20 ppm boron without development of hard spots.
