【 摘 要 】

The Deform-3D software was used to simulate and analyze the equal channel angular pressing (ECAP) of Ti-6Al-4V alloy with and without brass sheathing. The results show that the Ti-6Al-4V alloy samples with and without brass sheathing is both maintain a regular shape after ECAP. The effective strain of points on the cross section of sample with brass sheathing is smaller than that of sample without brass sheathing, but the extrusion load of sample with brass sheathing is smaller, and the difficulty of Ti-6Al-4V alloyin ECAP process was reduced. The experimental result also proves the feasibility of ECAP of Ti-6Al-4V alloy with brass sheathing, and the change of microstructure is accord with the deformation characteristic of ECAP.
