Simulation of subgrain growth during recovery is carried out usingtwo-dimensional discrete dislocation dynamics on a hexagonal crystal latticehaving three symmetric slip planes. To account for elevated temperature (i)dislocation climb was allowed and (ii) a Langevin type thermal noise was addedto the force acting on the dislocations. During the simulation, a randomensemble of dislocations develop into subgrains and power-law type growthkinetics are observed. The growth exponent is found to be independent of theclimb mobility, but dependent on the temperature introduced by the thermalnoise. The in-depth statistical analysis of the subgrain structure shows thatthe coarsening is abnormal, i.e. larger cells grow faster than the small ones,while the average misorientation between the adjacent subgrains remains nearlyconstant. During the coarsening Holt's relation is found not to be fulfilled,such that the average subgrain size is not proportional to the averagedislocation spacing. These findings are consistent with recent high precisionexperiments on recovery.
