The Formation of Microcrystal in Helium Ion Irradiated Aluminum Alloy

The Formation of Microcrystal in Helium Ion Irradiated Aluminum Alloy

A microstructure variation in Al-1060 alloy after helium ion irradiation was revealed by a transmission electron microscope (TEM). The result shows that ion irradiation produced dislocations, dislocation loops, cavities and microcrystals in the irradiated layer. Dislocation-defect interactions were...
