Analysis of growth rates of voids in the matrix and at precipitates in irradiated alloys

摘要: Abstract A characteristic feature of irradiated complex alloys is the correlated evolution voids, dislocations and seconday phase precipitates, with largest voids often adjacent to precipitates. Two mechanisms can be responsible for enhanced growth at The collector mechanism considers whole surface pair void—precipitate as a point defect sink. segregation accounts difference in radiation-induced near free precipitates corresponding segregation-induced biases. In this paper kinetic model size distribution functions isolated developed. By fitting calculations experimental data, effective bias G-phase neutron-irradiated 12Cr 15Ni steel calculated compared predictions mechanisms. effect on swelling rate analysed.
