“…Wang et al [1] studied the evolution of phase in the ring rolling of Ti-6Al-4V alloy by implementing a microstructure evolution model into the FE model. Similarly, Zhu et al [2] revealed the effects of deformation degree and initial forming temperature on the primary phase of TA15 titanium alloy in hot ring rolling process. However, these works only involved the pure radial ring rolling process, which is a single-pass rolling technology.…”

Abstract. The blank size, determining the deformation degree and the ratio of axial to radial feed amount of the radial-axial ring rolling process for TA15 titanium alloy, has a strong effect on the grain size and volume fraction of primary phase, which determine the mechanical properties of the rolled ring. In this paper, a macro-micro 3D-FE model of the radial-axial ring rolling of TA15 titanium alloy has been developed under ABAQUS software. The ring blank transferring from heating furnace to rolling mill, rolling and cooling after rolling during the whole process are considered in the FE model. And multiple blanks with different rolling ratios and ratios of axial to radial feed amount are designed for a desired TA15 titanium alloy ring. Then, the effects of the blank size on the grain size and volume fraction of primary phase in the rolled ring are investigated by comprehensive FE simulations. Finally, the optimum blank sizes are obtained by evaluating both the volume fraction of primary phase and the distribution uniformities of grain size and volume fraction of primary phase.

“…Some key modelling methods have been solved to obviously improve the precision and efficiency of numerical simulation, including elastic-plastic dynamic explicit algorithm (Utsunomiya et al, 2002;Sawamiphakdi et al, 2002;Luo et al, 2004;Zhang et al, 2007), mass scaling strategy (Qian et al, 2005), reconstruction and distortion control of grid (Davey and Ward, 2002a), adaptive control of guide rolls (Li et al, 2008;Zhang et al, 2012a), thermal-mechanical coupling skill (Song et al, 2002). In addition, some scholar have tried to use FE modelling methods to predict microstructure evolution of ring rolling, mainly utilising a FE software integrated a module to simulate microstructure evolution or developing a function in a FE software by compiling a subroutine, based on mathematical models of microstructure evolution Zhu et al, 2012;Henke et al, 2013;. As the deformation process of RRR has the characteristic of rapid variation and multi-nonlinearity, it is difficult to investigate the rolling course in detail by experiment.…”

Rings are basic mechanical components. Ring rolling is a well-known advanced plastic forming technique to manufacture high-performance seamless rings. Since the 21st century, the fast development of global manufacturing has raised an urgent request to high-performance rings, thus, comprehensive and in-depth studies on ring rolling technique were carried out. Based on long-term investigations and attentions on ring rolling, important developments of ring rolling theory and technique in recent 15 years were simply summarised, including the traditional radial ring rolling and radial-axial ring rolling, as well as the novel combined ring rolling. It is expected to give a valuable reference to the research and application of ring rolling.Keywords: ring rolling; theory; technology; equipment; recent development.Reference to this paper should be made as follows: Hua, L., Deng, J. and Qian, D.

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.
