Modeling phase separation and composition patterning in FeCrAl alloys at neutron irradiation

D O Kharchenko,
V O Kharchenko,
Jiantao Qin
et al.

Abstract: Possible scenarios of the microstructural evolution of FeCrAl alloys under neutron irradiation are studied by using the phase-field method. The exploited approach is generalized by considering ballistic mixing of atoms, spatial rearrangement of point defects, and dynamics of their sinks (dislocation loops), self-consistently. Stability diagrams manifesting domains of main control parameters (irradiation temperature, damage rate, atomic relocation distance) governing precipitation are obtained. It is shown… Show more
