Abstract
Abstract This paper presents the properties of warm forming of a B-pillar from 7075 aluminum alloy in state T6. Based on preliminary mathematical modeling, it was determined that the greatest strains and risk of aluminum cracking occur in the foot of B-pillar, therefore the forming process was simplified and conducted only for this part. The most important issue was to select the proper forming temperature and heating time, so as to preserve state T6 of the aluminum. Conducted tests demonstrated that the best mechanical properties without cracking were obtained for component place in a chamber furnace preheated to temperature 350°C. After approx. 5-6.5 minutes, it reached a temperature of 240°C.
