“…In recent years, combining the rapid solidification with roll bonding technology, a new short-flow process based on twin-roll casting (TRC) was successfully developed to fabricate bimetallic laminated materials. [16][17][18] In this work, taking the 304 stainless steel wire mesh as reinforcement, Al 1060 as matrix, a solidliquid cast-roll bonding (SLRCB) process based on the vertical TRC was presented to fabricate the stainless steel wire mesh-reinforced Al-matrix composite plate. And the interface bonding quality, microstructure, and mechanical properties were investigated.…”

Taking the 304 stainless steel wire mesh as reinforcement, Al 1060 as matrix, a solid-liquid cast-roll bonding process based on the vertical twin-roll casting was presented to fabricate the stainless steel wire mesh-reinforced Al-matrix composite plate. Optical microscope and scanning electron microscope were used to observe the microstructure of bonding interface, and the mechanical properties were investigated through tensile test and three-point bending test. The observation results show that there is no macroscopic defect at the bonding interface. Furthermore, atom diffusion occurs between the steel wire and aluminum matrix under the high temperature and contact pressure in the cast-rolling zone during solid-liquid cast-roll bonding process. The thickness of interfacial reaction diffusion layer is about 5 mm, and no separation was observed in the interface after three-point bending. The tensile test results indicate that the tensile strength and elongation rate of composite plate are improved with the increase in orientation angle of the steel wire relative to rolling direction, and the tensile strength and elongation are maximum when the orientation angle is 45°. In addition, there are two stress platforms in the tensile curve of the as-rolled composite plate due to the asynchrony of fracture between the reinforcement and matrix, but only one in the curve of as-annealed composite.

“…Huang et al [16] studied the effect of annealing temperature and time on the bonding strength of a Ti/Al cladding tape. After annealing at 520 • C for 25 h, the average bonding strength of the Ti/Al cladding tape increased from 21 N/mm to 27 N/mm.…”

Anisotropy is the difference in the microstructure or mechanical properties of materials in different directions. Anisotropic behavior occurs in rolled sheets, and this anisotropy is very obvious in laminated composites. In this work, the influence of anisotropy on the microstructure and mechanical properties of Ti/Al laminated composites fabricated by rolling was investigated. The results show that the microstructure and mechanical properties of the Ti/Al laminated composites were obviously anisotropic. The grains in the Al layer of the composites were elongated along the rolling direction and were compressed perpendicular to the rolling direction. The grains in the Ti layer of the composites had no obvious preferential orientation and comprised mainly twins. With the rolling direction as 0°, the mechanical properties of the Ti/Al laminated composites varied greatly as the angle of the composites increased. The tensile strength, elongation and bond strength of the Ti/Al laminated composites decreased with increasing angle of the composites. In addition, the microhardness of the Ti/Al laminated composites increased with increasing angle of the composites.

“…If the cladding of thin Ti sheet on to Al melt is achieved by the twin-roll casting, shortcomings of pure Ti or Ti alloys for applications to construction materials or components are effectively solved, while production costs are reduced. However, very few researches on liquid/sold bonding of Ti sheet and Al melt during the twin-roll casting have been performed 24 . Since the casting proceeds under a direct contact of a roll with a solidified Al melt shell and a thin Ti sheet, different approaches on the liquid/solid bonding are needed.…”

“…Since the casting proceeds under a direct contact of a roll with a solidified Al melt shell and a thin Ti sheet, different approaches on the liquid/solid bonding are needed. Even after the twin-roll casting would be successfully made, the bonding of Ti/Al clad sheets should be further enhanced because it is insufficient, but effects of microstructural and process parameters on the liquid/solid bonding have not been sufficiently studied yet 24 . Here we present a new fabrication process of Ti/Al clad sheets by vertical twin-roll casting and annealing, and analyze their microstructures and tensile properties.…”

Pure Ti or Ti alloys are recently spot-lighted in construction industries because they have excellent resistance to corrosions, chemicals, and climates as well as various coloring characteristics, but their wide applications are postponed by their expensiveness and poor formability. We present a new fabrication process of Ti/Al clad sheets by bonding a thin Ti sheet on to a 5052 Al alloy melt during vertical-twin-roll casting. This process has merits of reduced production costs as well as improved tensile properties. In the as-twin-roll-cast clad sheet, the homogeneously cast microstructure existed in the Al alloy substrate side, while the Ti/Al interface did not contain any reaction products, pores, cracks, or lateral delamination, which indicated the successful twin-roll casting. When this sheet was annealed at 350 °C~600 °C, the metallurgical bonding was expanded by interfacial diffusion, thereby leading to improvement in tensile properties over those calculated by a rule of mixtures. The ductility was also improved over that of 5052-O Al alloy (25%) or pure Ti (25%) by synergic effect of homogeneous deformation due to excellent Ti/Al bonding. This work provides new applications of Ti/Al clad sheets to lightweight-alloy clad sheets requiring excellent formability and corrosion resistance as well as alloy cost saving.
