Abstract null null Chain-die forming can be used to manufacture Advanced High Strength Steels (AHSS) channel components. Flange wrinkling is one of typical defects for chain-die formed products. The purpose of this paper is to investigate the cause of flange wrinkling in chain-die forming of AHSS and to propose a potential method to suppress it. A hat channel product with a curved axis is formed as a benchmark to illustrate the mechanism of flange wrinkling in chain-die forming. When forming suc...

Abnormally large grains (ALGs) appear after annealing of prestrained multiport extrusion (MPE) tubes, which will significantly degrade the mechanical properties of the tubes. In the present work, the underpinning mechanisms of ALGs’ formation are probed through experiments. MPE tubes made of A3102 alloy are prestrained by roll leveling with different thickness reduction ratios and are then subjected to annealing at 600 °C for different times. Microstructural evolutions during annealing are chara...

The pressure bearing capability of a folded multi-port flat tube (MPFT), which has the advantage of retaining the corrosion property of corrosion resistant materials, was investigated in this study with both a burst pressure test and finite element simulation. Results show that the folded tube’s failure is mainly caused by the breaking of the inner ribs. Instead of detecting inner pressure, the bulging ratio, which is supposed to be small under service pressure, rises rapidly before failure. The...

Chain-die forming is an emerging technique for manufacturing AHSS component as an alternative to roll forming. The pronounced springback of AHSS due to their high strength is a key factor in chain-die blocks design. In this paper, a modified Chaboche hardening model that assumes a Hollomon–Voce combined equation and incorporates variation of elastic modulus is established to better describe hardening behaviors of AHSS. An analytical method for rapid prediction of springback of a U-channel is dev...

The manufacturing process of multiport extrusion tubes generally includes homogenization, extrusion, roll leveling and heat treatment. In order to investigate the influence of the manufacturing procedures on strength variation of multiport extrusion tubes made of A1100 and A3102 alloys, the tube fabrication experiments and following materials characterization are carried out. The alloys’ stress–strain curves after every processing procedure are measured, and pressure-bearing capacity of the tube...

Abstract The cage roll forming process improves the flexibility of electrical resistance welding (ERW) pipes manufacturing by employing several groups of cage rolls, but poses great challenge to flower design and roll positioning, since the flower pattern and rolls’ positions are no longer one-to-one correlated as in conventional roll forming processes. In the present work, a forming flower design method for cage roll forming of ERW pipes is proposed, considering the transversal bending characte...

Microchannel tube (MCT) is widely employed in industry due to its excellent efficiency in heat transfer. An MCT is commonly produced through extrusion within a porthole die, where severe plastic deformation is inevitably involved. Moreover, the plastic deformation, which dramatically affects the final property of the MCT, varies significantly from location to location. In order to understand the development of the microstructure and its effect on the final property of the MCT, the viscoplastic s...
