Abstract
We study the coalescence of neighbouring voids along close-packed directions in recent computer simulation studies of void-lattice formation. The stability against coalescence of a developing void lattice is found to depend very much on the detailed geometry of the local void distribution. The possibility of void coalescence as an artifact, caused by the incorrect assumption of homogeneous void nucleation in these simulations, is suggested and discussed.
