Cluster Dynamics modelling of irradiation growth of zirconium single crystals

“…. Many models based on different mechanisms for irradiation growth have already been proposed in the literature [2][3][4][5][6][7][8]. Nevertheless, modelling of zirconium irradiation growth is still of interest for several reasons:…”

Dislocation loops growth and radiation growth in neutron irradiated Zr-Nb alloys: rate theory modelling

“…Models for irradiation growth with different mechanisms were proposed in the literature to describe the changes of material properties during irradiation of single-and poly-crystals [27][28][29][30][31][32][33]. Theoretical description of the radiation growth was developed by taking into account a diffusion anisotropy difference effect where diffusion of self-interstitials is anisotropic, whereas vacancy diffusion can be considered isotropic [34][35][36][37][38].…”

Component Radiation-Induced Dislocation Loops of Different Nature in Zirconium

“…[2,3] that interstitial loops are formed predominantly on the prismatic planes and vacancy loops on the basic. Although many models based on different mechanisms for irradiation growth have been proposed [4][5][6][7][8], Buckley's general concept has remained the same: vacancy loops nucleating and growing on the base planes "eating" the crystal along the c -axis, while growing interstitial loops, forming additional extra planes in the a -direction, increase its size. According [9] dislocation loops that form in zirconium under irradiation (electron or neutron) can be classified into two types according to their Bürgers vector.…”
