Abstrak

Bimetallic automotive components consisting of an Al–Si light alloy reinforced with a cast iron insert have been manufactured by gravity die moulding. Special precautions have been taken to ensure a uniform wetting of the insert by the liquid light alloy. Under these conditions, three intermetallic compounds are formed at the insert/alloy interface: η (Al5Fe2), T5 (Al7.4Fe2Si) and T6 (Al4.5FeSi). Upon subsequent heat treatment, T2 (Al5Fe2Si2) and T10 (Al12Fe5Si3) also appear. Growth of these compounds is discussed in terms of thermodynamics, kinetics and reaction mechanism in the Al–Fe and Al–Fe–Si systems. The effect of these chemical changes on the mechanical properties of the insert/alloy joint will be examined Keywords: B. Interface; E. Casting; E. Joining
