Hot Forming of 7075 Aluminium Alloy Tubes to Produce Complex and Strong Components

Simulation and Optimization of an Aluminum-Intensive Body-on-Frame Vehicle for Improved Fuel Economy and Enhanced Crashworthiness - Front Impacts

“…To form deep draw shapes and complex geometries, forming processes, such as superplastic forming, warm forming [39], hot forming [40,41,42], and hydro-forming processes [43,44,45,46,47], are needed to form automotive parts. Due to higher silicon content in the aluminum alloys, the abrasive nature of the material make dies wear out faster using aluminum sheets than with mild steel.…”

Three Point Bend Performance of Solutionized, Die Quenched and Heat Treated AA7075 Beam Members

“…Automobile fuel economy and emissions standards have become increasingly stringent in recent years and one method to meet these standards is to light-weight automobile structures with the implementation of precipitation hardened 6000-and 7000-series aluminum alloys. Although these materials offer an excellent strength to weight ratio, they suffer from low ductility at room temperature, which limits the complexity of the parts that can be formed in a conventional stamping operation [1][2][3]. Sotirov et al [1] and Beland and D'Amours [3] both showed excellent formability gains when AA7075 aluminum was warm formed at elevated temperatures in the range of 200-400°C.…”

Sotirov et al [1] and Beland and D'Amours [3] both showed excellent formability gains when AA7075 aluminum was warm formed at elevated temperatures in the range of 200-400°C. However, their work did not consider the as-formed properties of the warm formed parts.…”
