Analysis of shearing deformation in rolling-spinning forming of Ti-6Al-2Zr-1Mo-1V tubes

Abstract

Abstract. In this work, an analytical study of the macroscopic deformation and microstructure evolution of Ti-6Al-2Zr-1Mo-1V alloys during rolling-spinning forming process was performed by developing Finite Element (FE) modeling using the ABAQUS/Explicit platform. The developed FE model was validated by comparing with experimental results. To investigate the shearing deformation during rolling-spinning process, representative nodes were selected in the FE model. The shearing strains of these nodes were obtained by modeling. The influence of shearing deformation in rollingspinning forming process on microstructures was also analyzed. An optimal selection of process parameters was obtained to achieve better microstructure.
