Formation of novel microstructures in conventionally cast Al–Fe–V–Si alloys
The present paper reports the formation of novel morphologies of intermetallic compounds during the solidification of different Al–Fe–V–Si alloys using cooling rates ranging from 1 to 20 K s −1. The influence of cooling rate, composition of the alloy and the addition of Mg and Ni–20%Mg alloy on the...
