Abstract
WHEN the aluminium–silicon eutectic is rapidly frozen, or when sodium is added in small quantities (< 0.017 wt. per cent), the structure apparently is modified from an acicular form to a globular form of the silicon phase1–7. The reason for the modification is still a matter of controversy8, and a review of present-day theories is given by Chadwick1.
