Notes:
To meet the requirements of weight-saving and low-cost production of components forfuture transport vehicles, the concept of multi-material mix is of increasing importance. In thiscontext aluminum-iron compounds produced by means of compound casting are considered to be ofparticular importance. An essential and critical aspect of such compound castings is the formationof intermetallic phases (IMP) at the Al-Fe interface. Both the nature and the kinetics of potentialIMPs are not well understood and require a systematic investigation.In this paper we document the interface formation of pure Al and binary Al-alloys on a mild steelsubstrate by means of isothermal wetting experiments. Tests were carried out employing the sessiledroplet method in a controlled atmosphere. Using pure Al and Al7Si, Al7Cu, and Al7Zn alloys theinterface reactions were investigated by quantitative metallography (LOM, SEM/EDX). Specialattention was paid to the influence of the alloying elements on the type and sequence of IMPs at theinterface
