Abstract
IN a letter to NATURE of June 1, A. B. Greninger reports having observed twinning in alpha iron. Slow cooling through the A3 temperature produced twins of the banded type, whilst deformation and re-crystallisation resulted in twins which were seldom banded. It was shown by me in 19281 that certain strained and annealed alpha iron crystals contained twins lying along (112) planes, and furthermore I cited evidence suggesting that twinning in alpha iron might sometimes be associated with twinned gamma iron from which it had cooled. It has also been observed2,3 that on annealing a deformed single crystal of alpha iron the polygonal aggregate obtained gives pressure figures indicating uniform orientation, and it seems likely that this may also be associated with twinning.
