- •
Effects of four different preparation processes were studied at 20/60 °C.
- •
All NS + HT, RS and RS + HT processes can optimize the thermodynamic performance.
- •
The HT process can provoke the precipitation of A2B7 and leads to a poor cycling life.
- •
Al exhibits the most remarkable dissolution for all the alloys, especially at 60 °C.
