| 英文摘要: |
| Owing to the low cost, short process and low energy consumption, semi-solid rheoforming of Al alloys has been extensively employed to fabricate automotive and communication products. After nearly half a century of development, the focus of rheoforming of Al alloy has transformed from basic research to key technology and application research. This paper started with reviewing the current research progress in rheoforming of aluminum alloys at home and abroad, primarily comprising alloy design, semi-solid slurry preparation process, rheoforming and defect control, modelling and numerical simulation, and industrial application. Finally, special attention was paid to the future trends and prospects of rheoforming of aluminum alloys. The future development direction mainly comprises developing new alloy suitable for rheoforming, improving the production efficiency and stability of the slurry preparation, shortening new product development cycle while enhancing the comprehensive performance of the rheoformed parts. |
