Abstract
We investigated the microstructural stability of rapidly quenched Al-8 %Fe-2%Mo alloys by measuring the evolution of thermoelectric power dur ing ageing between 300 degrees C and 500 degrees C, and by transmissio n electron microscopy and small-angle X-ray scattering observation. Fo ur stages of evolution were found corresponding to the evolution of th e solid solution and S-phase into a final incoherent generalized preci pitation. The addition of Mo does not delay this evolution but gives a more homogeneous microstructure.
