摘要

The microstructure and the strengthening behaviour of Al-Fe-alloys (AA 1050-8021) is influenced by the alloy composition and the process parameter intermediate annealing. The element Fe has a very pronounced and positive effect on strength and elongation behaviour. With increasing Fe both mechanical values, tensile strength and elongation, increase in the O-temper condition and the resulting grain size is very fine and uniform. In addition to the Fe-content the process parameter, intermediate annealing, is important for the recovery behaviour, while through this process route thermal stability of the tensile strength is reduced. By controlling all these procedures it is possible to produce a high strength foil with good formability and a very fine grain structure.
