On the formation of intermetallics in rapidly solidifying Al–Fe–Si alloys

It is known from previous experimental observations that a rapid solidification of Al–Fe and Al–Fe–Si alloys results in the formation of various metastable phases. Despite attempts to explain why particular intermetallics form and to accurately predict a sequence of their precipitation, a fully satisfactory and prognostic explanation remains to be found. In this communication, it is conjectured that after the concept of the driving forces for …
