Dislocation climb mobilities, assuming vacancy bulk diffusion, were derived and implemented in dislocation dynamics simulations to study the coarsening of vacancy prismatic loops in face-centered cubic metals. When loops could not glide, comparison of the simulations with a coarsening model based upon the line tension approximation showed good agreement. Dislocation dynamics simulations with both glide and climb were then performed. Allowing for glide of the loops along their prismatic cylinders led to faster coarsening kinetics, as direct coalescence of the loops was now possible.
