Void evolution model-based forging process planning for compacting large steel ingots

WANG Zong-yang;FENG Chao;AI Hai-kun;YANG Hang;CUI Zhen-shan;

To enhance the predictability in the process planning for compacting large steel ingots, a compaction prediction method integrating void evolution model was developed through the secondary development technology of DEFORM-3D finite element software. The procedure was applied to simulate the evolution of void morphology and the compaction process response throughout the entire process from upsetting to radial compression of large steel ingots. Simulation analyses under various initial height-diameter ratios(H0/D0=1.0-2.0)and initial void aspect ratios(λ0=1-8) of steel ingots were carried out, which revealed the evolution laws of variables including void aspect fraction and relative volume fraction with process parameters.A void compacting process planning procedure based on “parameter calculation, constraint evaluation, and iterative optimization” was established. The results indicate that during radial compression, the initial void aspect ratio significantly affects the critical reduction rate for void closure. When λ0=8, the critical reduction rate is as low as 19.6%, whereas when λ0=1, the critical reduction rate reaches 28.4%. The proposed forging process planning procedure successfully characterizes the void compacting behavior in large steel ingots, with a prediction deviation within 7%, so that it establishes a robust, efficient, and precise method for void compacting process planning.

Cladding hot extrusion process of a novel nickel-based powder superalloy

MA Xiang-dong;PENG Wei-jin;XIAO Lei;GUO Jian-zheng;FENG Gan-jiang;

To address the issues of narrow hot extrusion process parameter windows, difficulty in controlling uniform fine-grained microstructure, and low effective material utilization rate of alloy materials for nickel-based powder superalloy, a combined approach of finite element numerical simulation and experimental validation was employed to systematically investigate the influence of different structural forms of cladding on hot-extruded bars during the cladding hot extrusion process of a new nickel-based powder superalloy FGH4113A(WZ-A3). The results show that the finite element numerical simulation results of the FGH4113A alloy hot extrusion process are in good agreement with the experimental results for both assembled cladding structure form and integrated cladding structure form. The macroscopic morphology entire hot extruded bar is rather straight. The microstructure is fine and uniform, and sufficient dynamic recrystallization has occurred. The average grain size is above ASTM 11.0. The effective material utilization rate of the FGH4113A alloy hot extruded bar has been significantly improved from 55.4% of the traditional assembled extrusion cladding structure form to 81.4% of the optimized integrated extrusion cladding structure form, effectively reducing the production cost.

Springback and cross-sectional distortion law in TA16 computer numerical control rotary draw bending forming

DAI Yi-cong;WANG Hui;YANG Qiu-cheng;YUAN Jun-tao;

To reveal the forming mechanism of TA16 titanium tube in CNC rotary draw bending forming, and to achieve precise forming and springback control, an elasto-plastic finite element model of the entire CNC rotary draw bending process for TA16 titanium tube was established based on the ABAQUS/Explicit finite element platform. The effects of mandrel extension and relative bending radius on tube springback and cross-sectional distortion were systematically investigated, and the reliability of the model was verified through experiments. The results show that as the relative bending radius decreases, the cross-sectional distortion rate and wall thickness reduction rate of the tube increase significantly. When R/D<3, the cross-sectional distortion rate exceeds the engineering allowable limit of 9%. The mandrel extension has a nonlinear impact on forming quality. Within the studied range, the cross-sectional distortion rate decreases monotonically from 11.28% to 9.82%, while the outer wall thickness reduction rate increases from 12.87% to 14.77%, with a smaller change in the inner wall thickness increase rate. The increase of mandrel extension reduces both the springback angle and springback radius, with a more significant reduction in the springback radius. A linear relationship model between the springback angle and bending angle is established, providing theoretical guidance and process reference for springback compensation in the actual production of TA16 titanium tube.
