“…This package was hot rolled after being pre-heated above the recrystallization temperature [22]. The local contact points between base steel and cladding alloy undergo plastic deformation under the high rolling pressure [11], so their area gradually expands, interesting the entire bonding surface. Under these conditions, the diffusion of the alloying element occurs, giving rise to the bonding interface, whose thickness continues to grow during the permanence at high temperature [23].…”

An integrated experimental-theoretical approach to the metallurgical characterization of the interfaces in steel plates clad by hot rolling is proposed. Three different couplings of materials have been studied: ASTM A 515 Gr.60 low carbon steel clad with austenitic stainless steel AISI 304L; extra low carbon steel ASTM A283 clad with high Ni content Alloy 59; and, low carbon steel AISI 1010 clad with Cu-Ni Monel 400. Experimental investigations, which are addressed to analyse the microstructural changes near the interfaces and identify the present phases, have been carried out through scanning electron microscopy (SEM) observations, microanalytical measurements by energy dispersive spectroscopy (EDS), and Vickers microhardness tests. In all of the cases examined, the zones that are affected by detrimental microstructural changes results in being considerably less thick than the overall cladding layer. Simulations that are based on theoretical diffusion modelling have been integrated to the experimental characterization by introducing a cladding parameter that acts on the diffusion bonding efficiency, in order to evaluate the effects of process temperature and time variations on diffusion bonding efficiency and stability. In particular, this analytical investigation has shown how the shorter is the duration of the diffusion transient and the higher the temperature, the lower results the sensitivity of the diffusion processes to temperature fluctuations.

“…Although each method has its own advantages, the hot rolling technique is the most common process due to its high efficiency and low cost [10]; moreover, it allows for obtaining products in the form of plates, bars, or reinforced tubes [11][12][13]. In addition, it can bond couples of metals with different mechanical properties [6].…”

“…Sun et al [8] proposed a modified element diffusion model based on the microscopic evolution mechanism in the transition zone, which could predict accurately the concentration distribution of atoms and the diffusion distance. Mudhaffar et al [9] found good mechanical properties for bimetallic steel at a preheating temperature of 1200 • C, rolling speed of 30 m/min, and reduction ratio of 32%. Wang et al [10] affirmed that the increase in rolling reduction rate improved tensile strength and interface deformation coordination and revealed that the interface bonding mechanism was related to the diffusion of elements, phase transition, and severe plastic deformation.…”

To ensure the long service life of concrete buildings in the marine environment, it is urgent to develop building materials with good corrosion resistance and weatherability. Stainless steel cladding is suitable for a highly corrosive environment and provides cost advantages. This paper investigated the deformation coordination and the microstructure evolution near the cladding interface of stainless steel/carbon steel. The stress-strain curves at different temperatures and strain rates were analyzed on the basis of high-temperature compression experiments. In addition, the sin-hyperbolic constitutive model was constructed, and the optimized parameters were obtained using electron backscatter diffraction characterization technology. The results show that at the deformation temperature of 1100 °C and the strain rate of 1 s−1, the deformation coordination increases significantly near the interface, accompanied by a large number of recrystallized grains, which has a positive impact on the comprehensive performance of the materials.

“…Cross et al [6] prepared a stainless steel clad rebar by the hot roll-cladding method, and the results of the microstructure, tensile test and impact tests indicated that the combination of core carbon steel and cladding stainless steel was not tight and a brittle fracture occurred during the mechanical test. Mudhaffar et al [2] studied the microstructure and mechanical properties of the stainless steel clad rebar by designing different passes and selecting different rolling process parameters. The results showed that the bimetal formed strong metallurgical bonding with better bonding performance.…”

In this study, a 304/20MnSi stainless-steel clad rebar was prepared by single-pass compression process using the MMS-200 Thermal Mechanical Simulator. The impact of different degrees of deformation and deformation temperature on microstructure evolution and the mechanical properties of stainless steel clad rebars were investigated. The study indicated that with the increase of the degree of deformation, the content of pearlite in a carbon steel matrix was increased, and the grains refined. The metallurgical bonding of the bonded interface was formed under high temperature and high extrusion force. With the increase of the deformation temperature, more bainite was obtained on the side of carbon steel, and the grain size increased. The obvious diffusion of Fe, Cr and Ni elements near the bonding interface resulted in higher microhardness of the stainless steel side and smaller microhardness of the carbon steel side. Moreover, the engineering stress-strain curves obtained by the tensile test showed that the plastic deformation of stainless steel and carbon steel was more coordinated. With the increase of deformation temperature and the degree of deformation, the tensile strength of the stainless steel clad rebar was as high as 690 MPa and the elongation was 26%, which was superior to the properties of the clad rebar prepared by other process parameters.
