Comments on the role of 1-D and 2-D self-interstitial atom transport mechanisms in void- and bubble-lattice formation in cubic metals

Abstract

It is pointed out that the early stages of void- and bubble-lattice formation in metals allows one to distinguish between linear and planar alignment of voids. Examples from voids in molybdenum and bubbles in aluminium clearly demonstrate planar rather than linear ordering. This letter also includes a rebuttal of a published criticism of an assumption made by the present author during a Monte Carlo simulation of 1-D self-interstitial atom (SIA) transport in void lattice formation.
