“…In particular, it was found that due to element diffusion (Fe, Cr, Ni, and Mn), a 20 µm thick diffusion layer forms between AISI 304 stainless steel and carbon steel clad plates. The diffusion layer is characterized by stable mechanical performance, and that microstructure does not show any grain growth [35], with internal mechanical properties showing a gradual change in the thickness direction [36]. Therefore, such a transition layer appears to be beneficial to a strong bond between stainless steel and carbon steel, also guaranteeing a stable transition of mechanical performance in the thickness direction.…”

This paper deals with carbon steel and stainless steel clad-plate properties. Cladding is performed by the submerged-arc welding (SAW) overlay process. Due to element diffusion (Fe, Cr, Ni, and Mn), a 1.5 mm wide diffusion layer is formed between the stainless steel and carbon steel interface of the cladded plate affecting corrosion resistance. Pitting resistance is evaluated by measuring the critical-pitting temperature (CPT), as described in the American Society for Testing and Materials (ASTM) G-48 standard test. Additionally, Huey immersion tests, in accordance with ASTM A262, Type C, are carried out to evaluate the intergranular corrosion resistance. Some hardness peaks are detected in microalloyed steel close to the molten interface line in the coarse-grained heat-affected zone (CGHAZ). Results show that stress-relieving treatments are not sufficient to avoid hardness peaks. The hardness peaks in the CGHAZ of the microalloyed steel disappear after quenching and tempering (Q and T).

“…The bonding mechanism and the interface microstructure have been extensively researched: it was suggested that the elements diffusion occurring between base and clad material represents a possibly key to understanding the bonding formation between the two metals [14]. Experimental observations that were carried out on carbon steels clad with austenitic stainless steel [15,16] showed microstructural changes that were associated with diffusion phenomena at the interface, highlighting how carbon diffusion from base to cladding material results in the formation of a decarburization layer at the carbon steel side and a copious carbide precipitation, with a significant local worsening of the corrosion resistance properties at the austenitic steel side.…”

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.

“…Therefore, the stainless steel clad plates have received more and more attentions in widespread applications in many fields, such as petroleum, chemical industry, ocean engineering, nuclear, building, transport, pressure vessels, paper machines, and so on . Recently, 90% of manufacturers adopt the vacuum hot rolling technology rather than overlay welding and explosive bonding to produce the stainless steel clad plates, which is attributed to the high efficiency, high precision, noiselessness, and low environmental pollution . Specifically speaking, compared with overlay welding and explosive bonding, stainless steel clad plates fabricated by hot rolling method can obtain stable, excellent microstructure and properties due to moderate cooling rate and little internal stress.…”

Series of 316L/Q235 stainless steel clad plates are successfully fabricated by hot rolling with different interlayers of ferrum (Fe), nickel (Ni), and niobium (Nb) foils. The interface microstructure, interfacial characteristics, shear performance, tensile properties, and fracture morphologies of clad plates are investigated using optical microscope (OM), ultra‐depth microscope, scanning electron microscope (SEM), electron probe microanalysis (EPMA), transmission electron microscope (TEM), and universal testing in detail. It is observed that the addition of Fe interlayer has rare effect on the interface element diffusion. Clad plate with Fe interlayer can only obtain poor tensile and shear properties, which is attributed to severe oxidation at the clad interface. On the contrary, the addition of Ni and Nb interlayers can both effectively inhibit the diffusion behavior of interface carbon element and remarkably reduce interfacial weak areas of carburized and decarburized layers. This is due to that Ni interlayer can sharply slow down the carbon diffusion velocity, and Nb interlayer can suppress interface carbon diffusion by reacting with carbon element and forming niobium carbide phase. After adding Ni or Nb interlayers, stainless steel clad plates can obtain superior interfacial bonding strength, tensile strength, and fracture elongation, eventually achieving the purpose toward strengthening and toughening the interface.
