Spray deposited SiCP/Al-Fe-V-Si composite is characterized with pores and oxide films between deposited particles, therefore further densification is needed. Densification of the composite preforms in large size has becomes the research emphasis and challenge. Current research of the composite is focused on densification technologies used to eliminate metallurgical defects. Key parameters of wedge pressing, density and stress distribution, flow behaviour, densification mechanism and regularity are investigated by combining experiment and finite element modelling. Pass reduction of 10%~15% and space of about 10mm between one end of the plate blank and the steel mould is beneficial to wedge pressing because of the effective deformation. Density and stress of the external layer are higher than that of the inter layer, density and stress distribution become uniform with overall reduction. Materials in preformed area flows along thickness direction as thickness of the plate decreases, while materials in main deformation area flows along length direction with increasing length of the plate. Wedge pressing of the spray deposited Al matrix composite plate follows porous metal plastic deformation mechanism under the condition of plane strain. Practical relative density of the plate is higher than the calculated value in the initial stage of pressing, while the practical relative density becomes lower than the calculated value as true strain exceeds 0.55, which can be attributed to the pores resulted from aggregation and breaking of SiC particles.

“…The rapidly solidified Al-Fe-V-Si alloy has a good high temperature resistance up to 350 • C so that there has been a considerable interest on this aluminum alloy [33][34][35][36][37] and its composites recently [38,39]. The materials based on Al-Fe-V-Si alloy may provide savings in the weight of structures by replacing titanium alloys or steels.…”

In this paper, the rheological properties of the feedstocks of Al-Fe-V-Si and Al-Fe-V-Si composites reinforced with alumina were investigated. The feedstocks, containing four different types of powder (Al-Fe-V-Si, Al-Fe-V-Si + 5 % Al2O3, Al-Fe-V-Si + 10 % Al2O3, Al-Fe-V-Si + 15 % Al2O3) and a polyethylene glycol based binder, were prepared. The volumetric fraction of the binder in the feedstock was varied between 37 % and 39 %. After the preparation of feedstocks, the rheology experiments were carried out using a capillary rheometer at various temperatures and pressures. According to the experimental results, the lowest viscosity values were found for the feedstock having the metallic powder. In addition, melt flow index was obtained to be within the range of 90-325 g/10 min for the investigated feedstocks and it increased with increasing temperature and pressure.

“…In addition, the tensile deformation behavior of the spray-deposited 8009Al alloy was investigated by uniaxial tension testing at temperatures of 250-450 °C and strain rates of 0.001-0.1 s −1 [4]. Furthermore, the high-temperature plastic deformation behavior of spray-deposited 8009Al alloy was examined by compression testing at strain rates of 2.77£10 −4 -2.77£10 −2 s −1 and temperatures of 350-550 °C [8]. Al-Fe-V-Si Al alloys were prepared by the method of electron beam melting, which exhibits grain microstructure and good mechanical properties [9].…”

at temperatures of 300-600 °C and strain rates of 0.1-4.0 s −1 [6]. The deformation characteristics of the rapidly solidified dispersion-strengthened 8009Al alloy processed by planar flow casting were studied by tensile testing at the temperatures of 25-420 °C and compression and hardness testing at 25 °C [7]. In addition, the tensile deformation behavior of the spray-deposited 8009Al alloy was investigated by uniaxial tension testing at temperatures of 250-450 °C and strain rates of 0.001-0.1 s −1 [4]. Furthermore, the high-temperature plastic deformation behavior of spray-deposited 8009Al alloy was examined by compression testing at strain rates of 2.77£10 −4 -2.77£10 −2 s −1 and temperatures of 350-550 °C [8]. Al-Fe-V-Si Al alloys were prepared by the method of electron beam melting, which exhibits grain microstructure and good mechanical properties [9]. SiCp/Al-Fe-V-Si produced by spray-deposited displays better-elevated temperature mechanical properties, tensile fracture behavior, and thermal stability [10,11].The content of reinforcement can be accurately controlled in any proportion via powder metallurgy (PM), and the reinforcement particles can distribute uniformly in the matrix, leading to stable performance and high production efficiency in the prepared material. The authors [12,13] previously investigated the characteristics and mechanisms of hot deformation and particle-reinforced mechanism of 8009Al matrix INTRODUCTIONAl-matrix composites reinforced with hard ceramic particles are widely used in the aerospace aera, defense department, and automotive industries because of their excellent performance including high strength, high stiffness, good corrosion resistance, light weight, and thermal stability [1-3]. Among these, Al-Fe-V-Si alloys and composites reinforced with ceramic particles are very broadly utilised at evaluated temperatures due to large volumes of very fine dispersed Al 12 (Fe,V) 3 Si particles. Thus, they are expected to be good heat-resistant substitutes for Ti alloys at 300-400 °C [4,5]. Nevertheless, reinforcement particles, such as SiC, TiC, and Al 2 O 3 , and/or high-volume fractions of very fine Al 12 (Fe,V) 3 Si induce poor formability and hot workability of Al-Fe-V-Si alloys and composites, thus their usage is limited.Most studies on deformation characteristics have focused on Al-Fe-V-Si alloys. The hot-working characteristics of rapidly solidified Al-8.5Fe-l.3V-l.7Si (8009) and Al-12.4Fe-l.2V-2.3Si (FVS1212) were investigated by isothermal hot torsion testing
