N2 - AlMn thin films were produced by evaporation of the Al1-xMnx alloys, with x = 0.10, 0.14, 0.20, 0.25 and 0.32, on NaCl substrates held at either liquid-N2 temperature or room temperature. The thin films obtained showed an almost amorphous structure. When these films were heated in situ in the transmission electron microscope, several phases of the AlMn system were observed during the amorphous-to-crystalline transition process produced. The structural evolution observed on the chemical composition and the thickness of the film. Some of these phases were Al6Mn, Al3Mn, Al4Mn, Al11Mn4, Al8Mn5, AlMn and quasi-crystalline phases. On comparison of our results with the AlMn phase diagram, it is concluded that this diagram does not reproduce completely the situation for thin films.
