“…Simulation parameter setting. The numerical simulation analysis is used to solve the filling problem on the forming time from such aspects as the forming temperature, blank size, flash thickness and the lubrication and the optimum temperature, optimum blank material size and the optimum flash thickness are determined [9,10]. We use the volume forming analysis software Deform 3D to simulate the three-dimensional finite element value of the new type synchronizing ring precision forming process and study the flow rule in the precision forging process and the effect of the upper die screw down speed on the synchronizing ring forming rule.…”

Synchronizing ring, an important component of automotive synchronizer, uses the friction torque generated on its conical surface to synchro-mesh the two meshing components to realize gear shift. In the paper the forming of the hot precision forging of the new synchronizing ring is analyzed based on the finite element numerical simulation method, which provides evidence for processing optimization and mould modifying to get an accurate blank. In addition, the one-step forming processing for the synchronizing ring is analyzed, and the flow of the material, forming process, flaw prediction and the optimization of the mould structure is studied as well. The result indicates that it is more reasonable of the distribution of the material and it is more satiation filled of the cavities. The cycle life of new product development is reduced greatly by forming process analyzing and flaw prediction of the synchronizing ring.

“…Productivity can be improved through SSM processing because of the shorter production cycle time than that in forging. Meanwhile, because the semi-solid slurries release less latent heat within the die cavity during solidification, the thermal shocks on the die are reduced and the die life is improved [6]. In addition, die wear may be lower than that in high pressure die casting due to the low injection speed.…”

Semi-solid metal (SSM) processing has been an attractive method for manufacturing near-net-shape components with high integrity due to its distinct advantages over conventional forming technologies. SSM processing employs a mixture of solid phase and liquid metal slurries and/or non-dendritic feedstocks as starting materials for shaping. Since the original development from 1970s, a number of SSM processes have been developed for shaping components using the unique rheological and/or thixotropic properties of metal alloys in the semi-solid state, in which the globular solid particles of primary phase are dispersed into a liquid matrix. In this paper, the progress of the development of shaping technologies and the formation of non-dendritic microstructure in association with the scientific understanding of microstructural evolution of non-dendritic phase are reviewed, in which the emphasis includes the new development in rheomoulding, rheo-mixing, rheo/thixo-extrusion and semi-solid twin roll casting, on the top of traditional rheocasting, thixoforming and thixomoulding. The advanced microstructural control technologies and processing methods for different alloys are also compared. The mechanisms to form non-dendritic microstructures are summarised from the traditional understanding of mechanical shear/bending and dendrite multiplication to the spheroidal growth of primary phase under intensively forced convection. In particular, the formation of spheroidal multiple phases in eutectic alloys is summarised and discussed. The concluding remarks focus on the current challenges and developing trends of semi-solid processing.
