| 英文摘要: |
| Platinum-based alloys have been widely used as functional materials. Studies showed that the addition of rare earth elements can effectively improve the performance of platinum-based alloys. The changes of strength, high-temperature stability and electrical properties of platinum-based alloys under rare earth micro-alloying and refining were reviewed herein. The solid solution strengthening, precipitation strengthening and dispersion strengthening mechanism and the refinement mechanism brought by micro-alloying were introduced. The properties of platinum-based alloys after the introduction of rare earths were summarized. It provides a reference for the research and development and application of new platinum-based alloy materials. |
