“…The Mg 17 Al 12 phase is adjacent to the AZ31B plate and the Mg 2 Al 3 phase is close to the 5052 plate. Lee [37] has reported a similar phenomenon in their research. The intermetallic compound phases generate at the interface between Mg and Al of a roll-bonded STS-Al-Mg three-ply clad sheet after heat treatment.…”

In this paper, Mg/Al laminated composites were successfully prepared at 400 °C by corrugated + flat rolling (CFR) with reduction ratios of 35% and 25% and subsequent annealing treatments were conducted at 200–350 °C for 30 min. A two-dimensional model was established to analyze the strain distribution during the first corrugated rolling process. Simulation results indicated that severe plastic deformation was formed at trough positions, which included more numerous refined grains than in the peak positions. The interfacial microstructure and mechanical property of the flattened composites along the rolling direction (RD) and the transverse direction (TD) were investigated. The results revealed that longitudinal discontinuous and transverse continuous interfacial intermetallic compounds (IMCs) were observed of the flattened as-rolled sample. Spatial distribution was provided for the grain microstructure along the thickness and rolling direction for AZ31B magnesium alloys of the CFR as-rolled composite. Mechanical property results showed that the longitudinal ultimate tensile strength (UTS) and elongation (EL) of the as-rolled sample reached 255 MPa and 4.14%, respectively. The as-rolled UTS along TD reached 325 MPa, about 30% higher than that along the RD. After heat treatment, the anisotropy of mechanical properties remained. The microstructure evolution and mechanical properties were discussed in detail.

“…Taking the values of YS and UTS calculated on the basis of ROM into consideration, the results provide strong evidence that experimentally measured tensile strengths for the 3-ply sheet fabricated by roll bonding adopted in this study are obviously improved, regardless of annealing treatment, which is primarily attributed to the adequate interfacial strengthening. However, it was also found that the difference between the experimentally determined and ROM-based tensile strength decreased upon increasing annealing time, which implies that the profound growth of the brittle IMCs at interfaces by overannealing have a detrimental effect on the mechanical interlocking at the interface [24,25]. Unlike tensile strength, an estimate of homogeneous composite strain cannot be supported by means of ROM theory [26].…”

“…Metal-clad plates for different applications have been developed in many industrial sectors [1][2][3]. Among them, carbon-steel plates cladded by stainless steel are one of the most widely used products since they allow one to combine the mechanical properties of carbon steel with the excellent corrosion resistance of the adopted clad.…”

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).
