Abstract

This review provides a comprehensive analysis of the current understanding of Fe-bearing intermetallic compounds (IMCs) in cast and wrought aluminium (Al) alloys, also covering their significance in recycling and sustainable materials development. It explores the various types of Fe-bearing IMCs, th...
