Notes:
Mechanical spectroscopy and neutron diffraction studies were performed on severalsamples with compositions Fe - 25 at. % (Al + Si) and Fe - 15 at. % (Al + Si). It was found that thesolute grain boundary relaxation is strongly dependent on the degree of order in the sample. Adecrease in the orderdegree allows the development of a relaxation peak at around 1000 K duringcooling from 1200 K. In contrast, if the order degree is not decreased, the grain boundaries remainlocked and consequently the relaxation peak does not appear. The magnetic response both in the asquenchedand after thermal treatment states was also explored and correlated to the microstructuralstate
