EFFECT OF FE CONTENT ON THE TRANSFORMATION OF FERROUS PHASES IN 6XXX ALLOYS DURING HOMOGENIZING ANNEALING

摘要

This work is devoted to studying the effect of Fe content on the processes of ferrous phase transformations in dilute Al-Mg-Si-Fe alloys by methods of quantitative metallography. The change of morphology of ferrous phases during homogenizing annealing is quantitative estimated. It is established that increasing of iron content to 0.4% in dilute Al-Mg-Si-Fe alloys accelerates the phase transformation.
