Research on forming properties of 7075 aluminum alloy tubes by power staggered spinning
Source abstract
Abstract
The present study employed the ABAQUS numerical simulation method to analyze the forward flow forming of 7075 aluminum alloy tubes using power staggered spinning compression materials. Subsequently, a power staggered spinning experiment was conducted to analyze the microstructure and mechanical properties. The simulation results revealed that increasing the spinning temperature led to a decrease in the limit thickness reduction per pass while increasing range, as well as enhanced deformation along the wall thickness direction. At 400 ℃, favorable forming properties were observed with minimal plastic strain occurring in the inner layer when thickness reduction is below 10%. These findings indicate that an escalation in total thickness reduction resulted in refined and uniform grain distribution along the wall thickness direction, accompanied by improved hardness (up to 178.6 HV) due to synergistic effects from fine grain strengthening, strain strengthening, and dispersion strengthening induced by second particles.
