ALLOYS flints C06C15/00; treatment of alloys C21D, C22F

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.

Groups C22C43/00 - C22C49/00 take precedence over groups C22C1/00 - C22C38/00.

This Note corresponds to IPC Note (1) relating to C22C1/00 - C22C38/00.

In groups C22C37/00 and C22C38/00, the last place priority rule is applied, i.e. at each hierarchical level, in the absence of an indication to the contrary, an alloy is classified in the last appropriate place that provides for one of the alloying components. This Note corresponds to IPC Note (1) relating to C22C37/00 - C22C38/00.

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 C22C1/00 - C22C43/00 or from groups B22F1/00 - B22F9/00.

In this subclass the special database "ALLOYS" is used. This system includes patent documents classified in groups C22C1/04 and C22C5/00 - C22C49/14 and provides information on the composition of the alloys, their uses and characteristics.

The following IPC groups are not in the CPC scheme. The subject matter for these IPC groups is classified in the following CPC groups: C22C101/00, C22C101/20 covered by
