The kinetics of phase decomposition in Al-Li alloys has been intensively investigated in the last decade. Experimentally, one or two precursory structures were first found by Nozato et al. in the late seventies by using differential scanning calorimetry (DSC). In order to clarify the nature of the dissolution peak appearing in DSC curves, the authors have conducted in-situ synchrotron-radiation (SR) small-angle and 100 scattering (SAS/100) experiments. During heating an as-quenched sample at the heating rate used in the present DSC experiments, the change of the small-angle scattering, representing the spatial distribution of solute concentration, as well as that of 100 profile, representing the spatial distribution of the local degree of order, has been measured. The structure change obtained from in-situ SAS/100 has been compared with the DSC results.
