ALLOYS (flints C06C 15/00; treatment of alloys C21D, C22F) [2013‑01]
NOTE

  • In this subclass, the following terms or expressions are used with the meanings indicated:
    • "alloys" includes also:
      • metallic composite materials containing a substantial proportion of fibres or other somewhat larger particles;
      • ceramic compositions containing free metal bonded to carbides, diamond, oxides, borides, nitrides or silicides, e.g. cermets, or other metal compounds, e.g. oxynitrides or sulfides, other than as macroscopic reinforcing agents;

    • "based on" requires at least 50% by weight of the specified constituent or of the specified group of constituents.
  • In the absence of an indication to the contrary, in groups C22C 5/00 to C22C 32/00 an alloy is classified in the last appropriate place.
  • In this subclass it is desirable to classify the individual aspects of combinations of processes or materials for powder metallurgy using Combination Sets with symbols chosen from groups C22C 1/00 to C22C 43/00 or from groups B22F 1/00 to B22F 9/00.
  • In this subclass the special database "ALLOYS" is used. This system includes patent documents classified in groups C22C 1/04 and C22C 5/00 to C22C 49/14 and provides information on the composition of the alloys, their uses and characteristics.
