Al-Zn-Mg-Cu-Li alloys%precipitate%microstructure parameters%aging%small angle X-ray scattering
Small angle X-ray scattering has been used to study the variation of microstructure parameters in an AlZn-Mg-Cu-Li alloy aged at various temperatures for various durations.Coarsening of precipitates was studied by analyzing the curve of kinetics strength vs the cube of radius.The results show that the coarsening of precipitates conforms to LSW principle.In addition,the characteristic of s3J(s)vs s curves was analyzed.The results show that the curves for samples aged at 160℃ for various durations(24,48 and 96 h)have negative deviation,which maybe resuits in the formation of certain new precipitate.In the other aging treatment states,the curves conform to Porod principle which means there is sharp boundary between the precipitates and matrix.
