Contents：

In order to improve the strength of Al alloys at elevated temperature, we systematically investigate the new mechanism, method and technique related to the fabrication and application of new crystal seed alloy, on the basis of atom cluster evolution and structural modulation in Al melts. A series of new crystal seed materials have been developed, including Al-P, Si-P, Al-B-C-N and Al-Ti-C-B-N alloys, which have been utilized in high-performance engine manufacture. We have also developed heat-resistant, high-strength Al alloys.
