Different degree of reduction and sliding phenomenon study for three-dimensional hot rolling with sandwich flat strip

Analysis of Bonding Behavior and Critical Reduction of Two-Layer Strips in Clad Cold Rolling Process

“…Afonja and Sansome [1], Pan et al [2] and Manesh and Taheri [3] have performed experimental works on the mechanism of pressure cold welding applicable in roll bonding. From theoretical viewpoint, Afonja and Sansome [1] based on the slab method, Tzou et al [4] based on the stream function method, Hwang et al [5,6] based on the upper bound theorem, and Lin and Huang [7] based on thermal-elastic-plastic coupled FEM model have proposed their own theoretical models to investigate the deformation behavior of the multilayer sheets in the rolling process. Afonja and Sansome [8] analyzed the sandwich rolling process.…”

Theoretical and experimental investigation of cold rolling of tri-layer strip

“…Vaidyanath et al [13], Park [14], McEwan and Milner [15], Tylecote et al [16], Mohamed and Washburn [17], Pan et al [18], Bay [19,20], Zhang and Bay [21][22][23][24], have provided a body of experimental data and on the basis of which have deduced many significant conclusion on the mechanism of pressure welding operative in cold-roll bonding. Also, Afonja and Sansome [25], Tzou et al [26], Hwang and Tzou [27], Hwang et al [1], Kiuchi et al [7], and Lin and Hwang [28] based on the slab method, the stream function method, the upper bound theorem and thermal-elastic-plastic coupled FEM model, respectively, have proposed their own analytical modNomenclature J * total shear power m 1 constant friction factor between roll and strip m 2 constant friction factor between layers O i center of cylindrical surface of velocity discontinuity R 0 radius of roll R i radius of cylindrical surface of velocity discontinuity t i initial thickness of tri-layer strips t f final thickness of tri-layer strips t hf final thickness of base layer (inner layer) t sf final thickness of clad layer (outer layer) t h0 initial thickness of base layer (inner layer) t s0 initial thickness of clad layer (outer layer) V linear velocity of roll V i amount of velocity discontinuity on the each surface of velocity discontinuity V f final velocity of tri-layer strip V 01 initial velocity of clad layer V 02 initial velocity of base strip W i shear power of the surface of velocity discontinuity…”

A simulation study on the multi-pass rolling bond of 316L/Q345R stainless clad plate

“…The second one was the bond criterion of stress. [14][15][16] Metals could be bonded as both materials being plastic stage and the normal pressure in the interface being up to or larger than the deformation resistance of harder layer material. Therefore, this criterion was adopted in this article because the normal stress and the flow stress of the interface at certain temperature and strain rate could be determined.…”

“…Zhang and Yang 12 built a twodimensional (2D) FEM model to predict bond results based on a bond criterion for laminated composites. Lin and colleagues [13][14][15] established a 3D thermal-elastic-plastic-coupled FEM model, and results containing deformation, the equivalent strain, shear stress, residual stress, and the rolling force were obtained. Zong and Zhang, 16 Dong and Wu, 17 and Xu and Zhang 18 determined the minimum relative reduction for perfect bonding by the FEM simulation of single-pass roll bonding process.…”
