The interface chemistry of the Fe/Al-13,5 wt% Si couple has been investigated at temperatures ranging from 600 to 800 °C. New data have been acquired on the phase equilibria in the Al-Fe-Si ternary system and on the kinetics of the interface reactions. A push out test has been developed to examine the relationships between the extent, thickness or composition of the insert/alloy reaction zone and the mechanical properties of the Fe/Al-Si joint.
