The aluminium content in steels is particularly important in the improvement of the yield ratio, ageing and magnetic properties, ductility (for marking sheets) and also in the primary metallurgy (continuous casting). From the metallurgist's viewpoint it is important to determine the soluble aluminium content only (i.e. AIN and Al solid solution) and the way this affects some of the mechanical properties. Conventional analysis is time consuming and cannot be employed on‐line therefore it would be useful to employ instrumental analysis. Several approaches have been investigated in the past using emission spectroscopy but this was found to be too complicated and expensive. A new method, described here, uses an X‐ray emission technique which yields good results and can be carried out on a commercially available X‐ray spectrometer without other facilities.
