Mechanical properties and reinforced mechanism of the stainless steel wire mesh–reinforced Al-matrix composite plate fabricated by twin-roll casting

Abstract

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.

Failure mode of reinforcing steel mesh in aluminum roll bonded composite material

“…In all cases regardless to reduction magnitude the destruction of mesh inlets was observed. The failure mode of wire mesh inlets observed in this research corresponds to that one described by previous authors [4][5][6][7]. The fracture is located at the zones of wires intersection as presented in the figure 3 (a).…”

“…Huang Теорія і практика металургії [7]. In all above-mentioned papers authors reported about significant rise of mechanical properties of composites due to application of wire mesh such as fracture toughness [2][3] and tensile strength [3][4][5][6][7]. Among all mentioned processes, for aluminum matrix, roll bonding seems to be the most perspective, since it allows much higher rate of manufacturing, it is simple to control the technology and there is no constrains in length of the product.…”

“…Application of strong inner core inside the soft metal matrix leads to sufficient rise of stress concentration in this hard material as a result of relatively high deformation plastic deformation magnitude of soft matrix [5][6][7][8]. Application of woven wire mesh as an internal core during roll bonding leads to appearance of zones with significantly intensified stress and strain at the location of wires intersection, this leads to possible fracture of wires during the manufacturing process [4][5][6][7]. In order to solve this problem, in this research it is decided to use expanded mesh instead of the woven one.…”

“…Moreover, this method was not limited by a variety of metals (Xunzhong et al, 2013). Also in order to manufacture composite reinforced by wire, the EXW were used (Los et al, 2010;Huagui et al, 2017).…”

Fabrication of Mesh Patterns Using a Selective Laser-Melting Process

“…A metal mesh, widely used in agricultural, industrial, transportation, and machine protection sectors, is a common type of metal screen consisting of parallel rows and intersecting columns [20][21][22][23]. A metal mesh can be made using intersecting wires by typically joining them together through welding or weaving.…”
