The study of the phase diagram for Fe-Al-Ge alloy. Its relation to the mechanical and magnetic behavior.
There exists very scarce information in the literature about the ternary Fe-Al-Ge system, which is related to some partial isotherm. In addition, information concerning the mechanical and magnetic properties of the Fe-Al-Ge system seems to be absent in the literature. The use of Fe-Al-Ge alloys in technological applications depends mainly on the brittle and creep behaviour at high temperatures. Dislocations and grain boundary mobility are the two most important mechanisms controlling the creep behaviour at high temperatures. Therefore, it is crucial to know the evolution of the phases in this ternary system, since it has a strong influence on the dislocation and grain boundary mobility. Consequently “in situ” neutron diffraction must be performed for determining the evolution of the phases in this ternary system. Neutron thermo diffraction is the most appropriate technique for studying the temperature phase transitions due to the short time involved to obtain the full spectra during the heating ramp in contrast to standard X-ray studies. For this proposal, 5 different samples (at.%): Fe-4Al-8Ge, Fe-8Al-4Ge, Fe-13Al-12 Ge, Fe-20Al-5Ge, Fe-25Al-2.5Ge; will be used.
