Abstract

The conditions for fully eutectic growth in Al-Fe alloys at a temperature gradient of 20 K mm−1 are reported for ranges of composition from 2.2 to 6.1 wt % Fe and of growth velocity from 0.03 to 10 mm sec−1. All six main classes of growth structure (i.e. Al-Al3Fe or Al-Al6Fe eutectics either alone or together with primaryαAl or Al3Fe) were obtained, some of them reported for the first time for steady-state conditions. Observed concentration-dependences both of the limiting growth velocity for primary Al3Fe and of the interphase spacing for the fully eutectic Al-Al6Fe displacing it are in good agreement with theory. Hardness levels for the Al-Al6Fe eutectic as a function of concentration are similar to those forαAl dendritic structures grown in much thinner sections under splat-cooling conditions. The significance of some observed transitions in growth morphology for eutectic cells, Al6Fe eutectic rods andαAl dendrites is discussed.
