“…According to recent studies on LMCs by methods of hot rolling [22,23] and hot pack rolling [24], the local shear of the component layers decreases with increasing rolling temperature, and our previous study [25] also proves that homogenous reduction of layer thickness can be obtained for laminated Ti-(SiC p /Al) composites by hot pressing followed by hot rolling.…”

Laminated Ti-Al composite sheets with different layer thickness ratios have been fabricated through hot pressing followed by multi-pass hot rolling at 500˚C. The laminated sheets show strong bonding with an intermetallic interfacial layer of nanoscale thickness between the layers of Ti and Al. The mechanical properties of the composites with different volume fraction of Al from 67% to 10% showed a good combination of strength and ductility. A constraint strain in the hot-rolled laminated structure between the 'hard' and 'soft' phases introduces an elastic-plastic deformation stage, more pronounced as the volume fraction of Al decreases. The thin intermetallic interfacial layer may also contribute to the strength of the composites. This effect increases with increasing volume fraction of the interface layer which thereby can contribute to the flow stress.

“…Finally, the two materials were embedded with each other (see Figure 7c), and the bonding strength of the two materials tended to be more strong with the increase in the reduction ratio. [ 22 ] Tabatchikova et al [ 29 ] and Liu et al [ 30 ] reported the same phenomenon when preparing the Steel‐based multilayer material.…”

To obtain a compatible material with good wear resistance (WR) and toughness, a composite material with high‐chromium cast iron (HCCI) dispersed in low‐carbon steel (LCS) is prepared through multilayer hot rolling. The microstructure and mechanical properties of the composite are investigated. The macrostructure of the composite material reveals that the HCCI layers are necked, fractured, and dispersed in LCS after hot rolling. The two materials combine well without unconnected areas and macrovoids on the interface; however, broken oxides are observed at the interface. Decarburization occurs at the LCS side near the interface and a 15−20 μm‐wide ferrite zone is formed at the LCS side. Fe, Cr, Mn, and C elements diffuse at the interface. A pearlite band is formed at the interface, and the thickness of the diffusion is about 2−4 μm. Due to the addition of ductile LCS, the impact toughness of the composite material is about 2.5 times higher than that of the as‐cast HCCI, whereas the WR of the composite material is lower than that of HCCI (about 16%). The dispersed HCCI in the composite produces a shadow effect during the sliding wear, which provides protection and support for LCS.

“…The vacuum hot rolling method is a prior and effective way to join the similar and heterogeneous metals at the intermediate temperature and vacuum environment . Due to that the carbon steel substrate and stainless steel cladding are heterogeneous metals; the affecting factors of interface formation mechanism are the key research topic for industrial applications of stainless steel clad plates . First, the interface bonding strength of stainless steel clad plates plays an important role in loading transport, formation of residual stress, fracture behavior, formability, weldability, and thermal and electrical conductivity.…”

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.
