“…Those who focus their analysis on the microstructure of the material do so through the experimental study of samples collected after the process. This is the case of Ding et al [23] who analyzed the resulting microstructure of magnesium alloyed seamless tubes, showing how the CPE process improved the UTS and elongation of the material.…”

The cross-roll piercing and elongation (CPE) is a forming process performed at high temperatures and high strain rates. The final product quality is strongly dependent on its microstructure. In this study, a finite element method (FEM) model was developed to better understand plastic deformation effects on microstructure during CPE and to analyze alternative thermo-mechanical processing routes. Specific models were used to simulate dynamic and meta-dynamic recrystallization (DRX and MDRX) for the processing of superaustenitic stainless steel (SASS). In addition, the CPE of SASS was investigated experimentally. The microstructure, mechanical properties, and chemical changes of the final product were assessed using optical microscopy, hardness testing, X-ray diffraction, and SEM-EDS. The results revealed higher temperatures and strain rates in the exterior area of the shell after piercing, and MDRX occurred in the whole thickness. However, an average grain size reduction of 13.9% occurred only in the shell middle and inner diameters. During elongation, the highest values of the strain rate and DRX were observed in the inner region, exhibiting a grain size reduction of 38%. Spread in terms of grain size and grain shape anisotropy was found to be less accentuated for tube samples as compared to the pierced shells.

“…A schematic representation of the parts involved in tube piercing is shown in Figure 17. Tube piercing is a complex process that involves exposing the material to extreme conditions, including ultra-high strain rates, high temperatures, and high process speed [120]. To maximize the lifespan of the tooling system and minimize energy consumption, it is essential to identify the best process parameters [121].…”

Rolling is one of the most important processes in the metallurgical industry due to its versatility. Despite its inherent advantages, design and manufacturing by rolling still rely on trial-and-error-based optimizations, which reduces its efficiency. To minimize the cost and time spent on the development of new rolling schedules, various analytical and numerical methods have been used in recent years. Among other alternatives, simulations based on the finite element method (FEM) are the most widely used. This allows for the analysis of the feasibility of new rolling schedules considering metal alloys with different characteristics, process conditions, or the creation of new operations, as well as the optimization of existing ones. This paper presents a literature review including the latest developments in the field of numerical simulation of rolling processes, which have been classified according to the type of rolling into the following categories: flat rolling, shape rolling, ring rolling, cross-wedge rolling, skew rolling, and tube piercing.

“…The three-roll perforator shares similar advantages with the two-roll perforator, including high e ciency, exible production, and the ability to penetrate long billets. However, its most notable feature lies in the deformation zone of the metal, which experiences three-way compressive stress [4,5]. Unlike the two-roll perforator, the three-way compressive stress eliminates the occurrence of center rupture.…”

A three-roll rotary piercing process (TRPP) with severe plastic deformation was conducted to fabricate stainless steel seamless tubes with high mechanical properties. To address production issues such as Front stuck (FS) -where the front end of the tube blank cannot be accessed, Back stuck (BS) -where the back end of the tube blank cannot be penetrated, and steelheaping, the process parameters were optimized through simulation and testing in this study. Additionally, a new structure for the three-roll piercing machine was designed and developed. The changes in roll feed angle and plug advance were systematically analyzed for defects in the tubular billet. Numerical simulations of the TRPP were performed using commercially available FEM software (Simufact Forming) to analyze the stress, strain, and temperature distributions in the pierced tubes. Experimental analysis was conducted on seamless tubes with different diameter defects, leading to the discovery of optimal rules. Based on the experimental and numerical investigations, it was found that optimizing plug advance and roll feed angle can enhance the forming quality of the tubes.
