| Outline of Final Research Achievements |
We observed the Suzuki segregation on the extended edge dislocations in Al-Mg-Si alloy. Under the aging at 573K, enrichment of Si on the Shockley partial dislocations. In Mg, similar enrichment around the Shockley partial dislocations was recognized. The segregation behaviors of over size and under size solute atoms are similar to that of the neutron irradiated austenite stainless steels. It is thought that segregation behavior of solute under aging and irradiation at elevated temperature. In the case of irradiated dislocations, it grow and moved in the matrix, in addition mobility of solute atoms are large. Therefore it is suggested that the solute atoms easily segregate to elastic field of dislocations or trapped directly on defects such as stacking fault and core of dislocations.
