“…Hence the relation between uniformly distributed TiB 2 particles and recrystallization is worth discussing. Numerous studies have been carried out to investigate the effects of second phase particles on the recrystallization [40][41][42][43][44][45] . It is well accepted that coarse nondeformable particles would induce recrystallization [40,41] while fine particles could either accelerate or retard recrystallization depending on deformation degree, interparticle spacing and annealing time [41,46,47] .…”

The in-plane anisotropy (IPA) of mechanical properties existed in plate products is often undesired since it limits the industrial application and increases the difficulty of material processing. It is thus one of the important factors which requires strict control during the manufacture of highperformance aluminum alloy plates. The anisotropic behavior of TiB 2 /2024Al composite rolling sheet under different heat treatment is studied in this article. T4 heat treated specimen shows good isotropy of yield strength and its texture components are significantly weakened compared with traditional Al alloys. The evolution of microstructures for T4 specimen was studied. The submicron TiB 2 particles increase the driving force of recrystallization during rolling process and static recrystallization (SRX) is stimulated, thus induces texture randomization. Anisotropic behavior of yield strength occurs in specimen after T3 heat treatment. It is supposed that the difference in the activation of slip system under different loading direction gives rise to this anisotropy.

“…It was reported that a strong deformation texture close to typical b-fiber was developed in the matrix, and reported that the intensities of the extrusion texture of 6061/SiCp nanocomposites decreased with increasing the volume fraction of SiC particles. The influence of particles on texture development in cold-rolled TiB 2 /Al composites was studied by Dan et al [34] It was found that particle-clusters were aggregated along grain boundaries, leading to a reduction of texture volume fraction due to the presence of randomly oriented grains near the cluster regions. In the current study, the presence of TiC particles should delay the formation of the b-fiber in the Al-TiC layer during the HRB process.…”

Microstructure and texture development in Al/AMCs sandwich composites and the connection between the tensile properties and microstructure/texture have not been fully understood. In this study, the AA 1060 aluminum alloy and spark plasma sintering (SPS) processed Al-TiC composite were prepared into the 1060/Al-TiC/1060 sandwich composites by hot-roll bonding (HRB). The influence of rolling reduction on the microstructure, texture and tensile properties was studied. An inhomogeneity of microstructure through the thickness of Al layer was observed after the HRB process. The grains at the surface Al layer were tilted to 19 deg with respect to the rolling direction after 34.8 pct reduction, and the tilted grains were developed to a deeper region with increasing rolling reduction. The degree of grain-subdivision and number of high-angle boundaries decreased as the observed area moved from the surface to the interface. The cube texture at the surface of the Al layer transformed into the rotated-cube shear texture during HRB process. The strength of the rotated-cube texture at the interface layer was lower than at the surface layer. The initial random texture in the Al-TiC layer was changed to the a-fiber and b-fiber rolling textures after the HRB process. The yield strength and ultimate tensile strength of the sandwich composites increased with increasing rolling reduction, and the sandwich composites showed a high elongation with 43.0 pct reduction.

“…Because of their high specific stiffness, light weight, good toughness and plasticity, good corrosion resistance and excellent wear resistance [ 3 ], B 4 C p /Al composites have attracted much attention from researchers and been successfully used for vehicle and body armors, aerospace structures, electronic packaging, fuel storage and nuclear radiation protection [ 4 ]. To fabricate such composites of high quality, various methods including stir-casting, squeeze-casting, pressureless infiltration and ultrasound-assisted casting have been employed [ 5 , 6 , 7 , 8 , 9 , 10 ]. However, they suffer from various drawbacks such as severe phase segregation, poor interfacial bonding, high cost, low efficiency and difficulty in manufacturing a component of a complex geometry.…”

Preparation of B4Cp/Al Composites via Selective Laser Melting and Their Tribological Properties

B4C-particle-reinforced Al (B4Cp/Al) composites are widely used in various areas, e.g., armors, electronic packaging and fuel storage, owing to their several outstanding properties including high specific rigidity, excellent wear resistance and light weight. Selective laser melting (SLM) is favored in manufacturing complex components because of its high raw material utilization rate and high efficiency. In this work, a B4Cp/Al composite was successfully synthesized by SLM, and the effects of one of the most important parameters, scanning speed (100–700 mm/s), on the phase composition, density, microhardness and tribological properties of the samples were investigated. The microhardness, relative density and dry-sliding wear resistance of as-prepared B4Cp/Al composites were improved with the decrease in scanning speed, and the sample fabricated at a scanning speed of 100 mm/s exhibited a relative density as high as about 97.1%, and a maximum microhardness of ~180 HV0.1 (approximately six times more than that of the SLM-formed pure Al sample, 31 HV0.1), a minimum wear rate of 4.2 × 10−5 mm3·N−1·m−1 and a corresponding friction coefficient of 0.41. In addition, abrasive wear, adhesive wear and oxidation wear were found to be behind the overall wear behavior of as-prepared B4Cp/Al composites.
