| C 22 K | INDEXING SCHEME ASSOCIATED WITH SUBCLASSES C21D, C22C OR C22F, RELATING TO CHANGING THE PHYSICAL CHARACTERISTICS OF ALLOYS [6] |
|
| Notes |
|
| (1) | This subclass constitutes an indexing scheme associated with subclasses C21D, C22C or C22F. The indexing codes should be unlinked. [6] |
|
| (2) | Attention is drawn to Chapter IV of the Guide which sets forth the rules concerning the application and presentation of the different types of indexing code. [6] |
|
1: | 00 | Changing the physical structure of alloys resulting in shape memory effect; Processes for stabilising or changing such effect; Alloys having shape memory characteristics [6] |
|
3: | 00 | Changing the physical structure of alloys resulting in superplasticity; Processes for stabilising or changing such effect; Alloys having superplasticity characteristics [6] |
