Effect of newly quenched forming on tensile properties of 2B06 aluminum alloy L profile

2B06 aluminum alloy profiles are widely used in the aviation field. In actual conditions, profiles need to be changed on the basis of the original shape or Angle. The more commonly used forming method is hard material forming, that is, direct forming through the traditional cold stamping. But the impact in the process of stamping may cause the material defects and lead to the deterioration of the mechanical properties of the profiles. And aluminum alloy in the newly quenched state has better plasticity, the stamping process produces smaller springback and surface defects. In this paper, 2B06 aluminum alloy L profile is taken as the research object. The L profile is changed from 90° to 93° by newly quenched forming and hard forming respectively. Compared with the traditional hard material forming process, the influence of the new hardening process on the mechanical properties of the profile was explored. The microstructure changes were further explored by metallograph observation and SEM scanning. The experimental results show that the mechanical properties of the newly quenched profiles are improved obviously, the plasticity of the profiles is improved to a certain extent, and the failure load is increased by 14.8 percent. The tensile fracture of the newly quenched profile is ductile fracture, and the composite fracture of dimple and quasi-cleavage plane is formed by hard material forming.
