Radiation-induced segregation of nitrogen implanted into iron

Radiation defects are important to nitrogen migration and mapping which is identified as radiation-induced segregation. Radiation defects are studied using nuclear reaction analysis and secondary-ion-mass spectrometry. The coupling between nitrogen atoms and the radiation defect flux determines the radiation-induced segregation process which is due to nitrogen-vacancy complexes. The nitrogen mechanism depends on the number of freely migrating defects created during an implementation.
