Influence of nano-SiCp on the foamability and microstructure of Al/TiH2 foam sheet manufactured by continual annealing and roll-bonding process

Investigating of the Microstructure and Mechanical Properties of Al-Based Composite Reinforced with Nano-Trioxide Tungsten via Accumulative Roll Bonding Process

“…The roll bonding technique has been extensively used to fabricate nanocomposites because of its low cost and efficiency. This method has two important strengthening mechanisms, one is formation of Nano/UFG structure by SPD and the other is reinforcing metal matrix by ceramic particles [10] [11]. Metal matrix composite materials are a group of particles reinforced by ceramic particles, layers or whiskers that have unique physical and mechanical properties [11] [12] [13].…”

“…Addition of ceramic reinforcements (i.e. carbides and oxides) to the metal matrix composites enhances the properties such as elastic modulus, strength, wear, corrosion resistance, hardness and high-temperature durability [11]. In this research, tungsten trioxide (WO 3 ) nanoparticles with the density of 7.16 g/cm 3 were used as the reinforcement material.…”

Significant improvement in structural features, mechanical and physical properties of a novel CAR processed Al foam by nano-SiCp addition

“…Closed-cell metal foams, particularly aluminum foams, are widely used in structural engineering applications and building constructions because they provide lightweight structures with high ratios of stiffness and strength to weight, remarkable energy absorption capabilities and suitable damping properties [1,2]. These characteristics of metallic foams strictly depend on pore architecture (diameter, uniformity and shape) and cell skeleton properties (thickness and strength) [3][4][5].…”

“…These characteristics of metallic foams strictly depend on pore architecture (diameter, uniformity and shape) and cell skeleton properties (thickness and strength) [3][4][5]. Addition of ceramic particles, specifically SiC, Al 2 O 3 or TiB 2 , to the metallic matrix offers one of the existing strategies to obtain the desired quality [2,6]. For instance, Kennedy et al [7] verified that these particles were able to increase maximum expansion of P/M Al foams by decreasing the critical cell wall thickness before rupturing phenomenon.…”

“…Preparation of a foamable precursor using accumulative roll-bonding (ARB) or continual annealing and roll-bonding (CAR) processes followed by subsequent foaming heat treatment is one of the recent attempts of this progression [2,10,11]. Over the last decade, Kitazono et al [12][13][14] have traced the advance of the ARB process in production of foamed sheet Al alloys.…”
