Magnesium Twinned Particles Grown in Inert Gases

Abstract

Twinned particles of magnesium prepared using the gas evaporation technique were studied using electron microscopy. Particles with (10.1), (10.3), (11.1) and (11.2) twin planes were found in the smoke outer zone. Their external faces were the same as those of single crystal particles, i.e. {10.0} and (00.1). The growth of the (10.1) twinned particle was more pronounced than that of the other three kinds of twinned particles and from this it was deduced that the twin formation occurs at the nucleation stage.
