Abstract

The objective of the present work is to investigate the formation of intermetallic compounds such as iron aluminides and oxides during the formation of an alloy by melting commercially pure aluminium (Al) billets and adding iron powder (Fe) at 750 °C in the molten aluminium. The exothermic reaction during the addition of ‘Fe’ in the molten ‘Al’ resulted in the formation of more amounts of intermetallic compounds because of the rise in temperature. The composition of the ‘Al’ and ‘Fe’ powder was varied to obtain various alloys. The optical microscopy examination revealed the presence of various intermetallic compounds and oxides in the matrix. The Rockwell hardness survey performed on various samples exhibited a maximum hardness value of 79 in ‘B’ scale for the alloy composition of 60% Al and 40% Fe. A maximum shear strength of 288 Mpa was obtained for the samples containing 65% Al and 35% Fe. © 2021, Springer Nature Singapore Pte Ltd.
