Application of Electronic Probe for Homogenizing Heat Treatment of 6063 Aluminum Alloy

The application of electronic probe for homogenizing heat treatment of 6063 aluminum alloy was studied, through the different homogenizing heat treatment process of the alloy, the second phase of its forms, quantity and distribution were observed by means of electronic probe, the corresponding state in the second electronic images (SEI) and surface scanning photograph of Fe, Si and Mg were gotten. As the spread degree of Fe and Si is lower, thus primarily through observation of the elements distribution chart of Mg and SEI before and after the homogenizing heat treatment, and combining energy dispersive X-ray diffractometry (EDS) analysis on the chemical composition of alloy micro district and the second phase, the superiority and weakness of the homogenizing heat treatment process were judged.
