Twin Crystal Inclusions in Aluminium and Iron

Article metrics

Abstract

The communication by Messrs. May, Tiedema and Burgers1 reports the existence of minute unabsorbed crystals embedded in parent grains of aluminium and having a twinned orientation to the parent. Iron resembles aluminium in seldom showing annealing twins with typically straight boundaries. Twenty years ago2, I reported upon some small ferrite crystals embedded in large recrystallized grains of iron, and found that they were twins of the parent. One of my suggested explanations of their occurrence was "unabsorbed grains of the original fine-grained aggregate whose orientations were by chance relatively twinned to that of the large crystals which eventually grew round them". This is the view now put forward for aluminium by Burgers et al.
