| Table 1 Design methods of single crystal superalloys |
|
| Design method | Country | Key concept | Shortcoming |
|---|
ADP | Japan | Computer regression processing based on a large number of experiments | The relationship between alloy strength and elements was not established based on strengthening mechanism | ABD | England | Introduce some limiting parameters and filtering through big data computing | The element distribution and interface strengthening were not considered | MultOPT | Germany | Based on multi-standard optimization and semi-empirical model | The precipitation?strengthening and interface strengthening were not considered in detail |
