In this work, a novel constrained ring rolling of the deep groove ring is proposed, which can make the ring into a multi-point constrained deformation state by changing the control mode of guide roll and conical roll, limiting the circumferential metal flow ability and promoting the axial and radial metal flow ability, thus realizing the coordinated forming of the ring diameter and section profile. The evolution law of the ring geometry, metal flow deformation behavior, and the mechanical states between the roll and ring under the traditional ring rolling and constrained ring rolling were compared and analyzed by FE simulation. The influence of guide roll and conical roll motion control parameters was further studied and found that guide roll motion and conical roll speed have great influence on ring forming.

Despite the application of upsetting to remove internal voids in ingots, defects are often not fully eliminated by the end of the process. To address this challenge and produce upset ingots with minimal internal defects, this study introduces a novel approach. The first step involves simulating the formation of shrinkage porosity during ingot solidification and identifying the critical zone prone to internal defects. Subsequently, the study analyzes the effective strain distribution and mean stress in different sections of the critical zone using various upsetting anvil geometries. An optimized approach is then proposed, involving the shifting of the critical area to where the most significant plastic deformation is likely to occur. This is achieved through a new pin-making strategy and the selection of the best geometry for the pair of upsetting dies. To validate the model, 100CrMo7-3 heavy ingots are produced and subjected to upsetting and cogging operations using a 63MN hydraulic press. The results from ultrasonic and microscopic examinations indicate that the proposed method leads to fewer internal imperfections. Additionally, a comparison between numerical and experimental results demonstrates good agreement, resulting in a reduced risk of remaining internal shrinkage porosities after upsetting large-scale ingots.</p></div>","PeriodicalId":591,"journal":{"name":"International Journal of Material Forming","volume":"18 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These profiles require rapid (water) quenching as they leave the press in preparation for age-hardening. Conventional rapid quenching, which only directly cools the profile’s extremity, can distort the part. Lower quenching rates reduce distortion but may compromise the mechanical properties. We test three hypotheses: (1) That the different cooling rates across the section during quenching induce varying mechanical properties as well as distortion; (2) That this temperature differential can be minimized by combining novel internal profile quenching with conventional quenching; and (3) That internal quenching can be achieved using insulated channels in the extrusion die to convey the quenchant to the profile’s interior. The first hypothesis is tested experimentally by taking tensile specimens from a AA6082 multi-hollow profile. The second is examined experimentally using a lab-built quench box and theoretically using thermo-mechanical finite element simulations. The third hypothesis is tested by conducting a hollow profile extrusion trial using a specially designed porthole die. The testing shows that conventional quenching results in reduced mechanical properties in the profile’s internal walls but that combined external/internal quenching alleviates this problem and reduces distortion. The extrusion trial on internal quenching demonstrates die survivability, an acceptable die temperature drop during quenchant flow, and effective quenchant disposal via evaporation and capture of liquid at the end of the profile. This study suggests that internal quenching is a promising technology option for reducing scrap and improving mechanical properties of hard-to-quench aluminum profiles.</p></div>","PeriodicalId":591,"journal":{"name":"International Journal of Material Forming","volume":"18 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, forming high-ribbed spokes is challenging due to potential shrinkage during high rib extrusion with plane strain characteristics. This study utilizes the finite element method to analyze the high-rib extrusion process with plane-strain characteristics. It is found that a region of tensile stress exists near the bottom fillet of the rib persisting until the high rib contour is fully filled. The position and size of this region remain largely unchanged during extrusion. Defining the occurrence of shrinkage defects as a critical state, the thickness is defined as the critical residual thickness. By constructing a stress state slip line field for plane-strain extrusion, a prediction formula for the critical residual thickness of high-rib extrusion is proposed. The proposed critical residual thickness is evaluated through finite element calculations and high-rib extrusion experiments. The results show that the critical residual thickness is linearly positively correlated with the half-width of the rib root and negatively correlated with the fillet radius of the rib root, taper angle, and shear friction coefficient. The initial blank thickness does not affect the critical residual thickness. The depth of the shrinkage increases linearly with the decrease in residual thickness. The experimental critical residual thickness can be determined by combining finite element calculations and extrusion experiments. The proposed theoretical formula for the critical residual thickness has an error of + 8.14% compared to the experimental critical residual thickness. This theoretical prediction is relatively conservative and can guide the design of high-rib extrusion forming billets to ensure defect-free high-rib forming.</p></div>","PeriodicalId":591,"journal":{"name":"International Journal of Material Forming","volume":"18 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143379768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This ML-driven digital twin approach also provides a robust proof of concept for addressing initial charge shapes in complex three-dimensional (3D) molds, where the computational demands of reverse flow simulations may present challenges.
