To improve the formability of aluminum alloy sheets and avoid springback, a newly developed forming technique, HFQ (heat-forming-quenching), has attracted attention in the automobile industry. In this work, a high-temperature tensile test and the Nakazima hemispherical punch method were used to simulate the HFQ process to study the high-temperature flow
Three-dimensional tensile strength of the FSWed joints are examined throughout the hemispherical-punch stretching (HPS) method. • Forming limit of the 7075-T6 sheets are declined due to the microstructural effects of the FSW. Abstract. The present research aims to investigate the effects of friction stir welding (FSW) on the microstructure and mechanical

7075 Aluminum Alloy Stretching Sheet 7075 Aluminum Alloy Stretching Sheet is one of the highest strength aluminum alloys available. It has good machinability and an excellent strength to weight ratio, and it is a popular materials in applications where strength is extremely critical. 7075 aluminum plate sheet is often used for highly stressed parts, and has average corrosion
In order to achieve different strain paths, loads that generate different strain paths are applied to the sheet specimen, so that uniaxial stretching becomes biaxial stretching. In recent years, many scholars have conducted research on 7075 aluminum alloy hot stamping. Xiao et al. studied the influences of process parameters such as blank temperature, stamping
