An experimental investigation into the formability of hydroforming 5A02 Al-tubes at elevated temperature

Improvement of Die Corner Filling of Stepped Tubes Using Warm Hybrid Forming

“…They showed that with respect to room temperature, the formabilit y increases at elevated temperatures. The same result was obtained by Yuan et al [9] in uniaxial tension and hydrobulge tests for 5A02 aluminum tubes. Kim et al [10] investigated the free bulge test of AA6061 alloy tube using experiment and finite element simulation by DEFORM-2D software.…”

Hot Tube-Forming

“…Yuan et al (53) investigated the tensile behavior of 5A02 Al tubes at elevated temperature. It can be seen from Figure 30 that the uniform elongation increased rapidly at higher temperatures, and the strength coefficient K value decreased quickly as the temperature is increased.…”

Hot Gas Forming of Aluminum Alloy Tubes Using Flame Heating

“…Since internal gas pressure is compressive and the volume of the pressure medium is automatically expanding, it is difficult to control the deformation behavior. Most often, electrical resistance or electromagnetic induction methods are used to heat tubes [8][9][10][11][12]. However, Joule heating requires a certain electrical resistance for heating materials, and it is not suitable for heating an aluminum alloy with a high electric conductivity.…”
