Effect of extrusion pass on ECAP deformation of 2024 aluminum alloy

  • Received Date: 2019-12-17
  • Taking 2024 aluminum alloy as the research object,Deform-3D finite element software was used to conduct numerical simulation of the specimen and 8-pass ECAP experiment of path A,and the changes of metal fluidity,extrusion load and equivalent strain in the deformation process of the specimen under different extrusion passes were studied.The results showed that the metal flow mesh in the head and tail region of the specimen presented bending deformation,while the central region presented pure shear deformation and the deformation degree increased significantly with the passes.The extrusion load increased first and then decreased with the increase of the extrusion pass,which was affected by the strength of the specimen.The size of the equivalent strain value of the specimen was proportional to the number of extrusion passes,and the equivalent strain value was distributed in layers from large to small from the area near the inner corner of the specimen,and the uniformity of strain distribution decreased after 3-pass.
