“…With the development of large launch vehicle technology, an increasing demand persists for large-diameter, high-strength thin-walled cylindrical components. Given the difficulties in manufacturing mandrels, the uneven deformation of the inner and outer surfaces of the cylinder, the traditional spinning is no longer suitable for manufacturing cylinders with a diameter of over 2.5 m (Luo et al, 2018). Counter-roller spinning (CRS) replaces the mandrel in the traditional spinning with inner rollers, the principles of traditional spinning and CRS are shown in Fig.…”

As an advanced plastic-forming method, counter-roller spinning (CRS) is mainly applied to process large-sized, thin-walled cylinder for aerospace rocket engine. Medium carbon quenched and tempered steel 30CrMnSiA is a typical material for solid rocket motor due to its high strength, high toughness and good fatigue resistance. The determination of complex process parameters and the detection of multiple forming indexes are necessary for the study of CRS. In this paper, a finite element (FE) model for CRS of 30CrMnSiA cylinder with a diameter of 2.25 m was established and verified according to the experimental data. The effects of multiple process parameters on the forming results were studied and analyzed by orthogonal experiment. Results reveal that the thinning ratio is the most important process parameter for all the forming results. Larger thinning rate can improve production efficiency but reduce forming accuracy and require equipment to provide greater spinning force. The influence laws of process parameters on the forming accuracy and spinning force of the outside of the cylindrical parts are similar to that of the inside of the cylindrical parts. In addition, the forming accuracy error and spinning force of the inside of the cylindrical parts are smaller than that of the outside of the cylindrical parts. Thus, the forming force and positioning accuracy of the outer roller holder can be given priority when developing the CRS equipment. Based on the ANOVA results, a multivariate nonlinear regression analysis was performed on the forming results by selecting significant process parameters as independent variables. The optimal range of process parameters for obtaining good forming results was obtained by processing the regression equation.

“…As a kind of local incremental forming technology, spinning has great advantages of high dimensional accuracy and low forming force in manufacturing rotational parts through accumulating multiple small strains [14][15][16][17]. Unfortunately, spinning prefers to cause the fracture and under lling of ribs, so it is hard to manufacture high performance parts with ribs [18,19]. Isothermal forging and extrusion are also the important way to form thin-walled component with ribs [20].…”

Plates with rib-web structure of magnesium alloys can hardly fabricated through conventional method. In this work, the variable circular channel angular extrusion (VCCAE) combined extrusion and severe plastic deformation is proposed, in which billet undergoes severe deformation at several variable circular angular channel. The FE model for VCCAE of scaling plate with ribs is established and the experimental set up is designed. The feasibility of the novel process and the accuracy of the FE model are validated by the simulations and experiments. Stress state and the effective strain distribution in longitudinal section and cross section are analyzed. The results show that stress and strain distribution in longitudinal section is extremely inhomogeneous, and obvious stress concentration at the shear plane is founded. The microstructure in angular region is more uniform and ner, which validate that the severe shear deformation induced by the angular channel in the VCCAE process could promote the deformation uniformity and grain re nement. The results of numerical simulation and experiments demonstrate that the VCCAE process proposed in this paper is feasible and it has great potential to manufacture highperformance plate with ribs.

“…At present, composite spinning-extrusion (CSE), which combines the advantages of both spinning and extrusion processes, is considered as a new method for the integral formation of ribbed ring cylinders (Domack and Wangner, 2015;Tayon et al, 2019). However, current research on the integral formation of ribbed cylindrical parts is still in the exploration stages, and most of the relevant reports focus on the optimization of process parameters such as temperature, thinning rate, and feed ratio (Zeng et al, 2020;Luo et al, 2018;Zhan et al, 2016;Zhan et al, 2016;Abd-Eltwab et al, 2017;Lin et al, 2018;Xia et al, 2018;Xia et al, 2019). At present, there is no report on the preparation of ribbed ring cylinders through Al-Cu-Li alloy CSE forming.…”

The regulation of blank microstructure is the key to manufacturing high-quality ring cylinder by composite spinning - extrusion forming. In this paper, the precipitation morphologies of three Al3Zr dispersions were obtained by changing the heat treatment process, and their effects on the microstructure and mechanical properties of Al-Cu-Li alloy ring cylinder were investigated. The results show that the microstructure and mechanical properties of ring cylinder are affected by the different precipitation distribution of Al3Zr dispersoids in the blank. When the Al3Zr dispersoids precipitated and dispersed, the cracking of ring cylinder was eliminated, the thickness of coarse-grained layer decreases obviously, and the elongation is increased by 33.5%. In the T83 state, the average length of the T1 phase decreased from 100.3 to 77.5 nm, while the tensile strength and yield strength of ring cylinder increased by 16 and 20 MPa, respectively.
