Rapid preparation method of copper alloy standard sample |
| abstract |
A method for rapidly preparing a copper alloy standard sample comprises the following process flow steps: composition design → material preparation → smelting → casting → segregation test → uniformity inspection → peeling and finishing → scrap extraction and value determination; the invention greatly shortens the smelting period, reduces the use of materials and reduces the production cost. |
