Precipitate Extraction From 3003 Aluminum Alloy Produced by Twin Roll Casting/ Extração Precipitada De 3003 Ligas De Alumínio Produzidas Por Fundição Em Rolo Duplo

Abstract

In the present study four different precipitate extraction techniques were investigated on a 3003 aluminium alloy samples (twin-roll cast and homogenized conditions). The dissolution product was analyzed with the help of X-ray diffraction, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analysis. The performance of four chemical solutions (iodine solution, perchloric acid, oxine solution, and phenol solution) was compared, and the phenol solution presented the best precipitate extraction results. The phases in the cast and homogenized microstructures were identified, explaining some aspects of the phase transformation during the homogenization.
