“…10 g. The EDS mapping analysis shows that the periphery of the cracks is agglomerates composed of TiB 2 and Cu-containing phases. The matrix around these agglomerates has minimal slip space, and its local deformation is more significant than the near-planar interface [23] , which can be a source of cracks. Figs.…”

“…The results of the quantitative EDS analysis of the two regions A and B in figure 8(B) are shown in table 3. Previous studies [23,24] pointed out that TiB 2 particles in extruded composites were mainly distributed in two regions; one region exhibited a strip-like structure consisting of S-and θ-phases together; the TiB 2 particles in this region were larger and could be easily detected as agglomerates. In the other region, the TiB 2 particles were uniformly distributed in the gaps of the strip-like structures, and were usually difficult to detect due to their smaller size and more diffuse distribution.…”

TiB2/2024 aluminum matrix composites were prepared in situ from the Al–K2TiF6–KBF4 reaction system; then, we investigated the microstructure and mechanical properties of the composites in the as-cast and extruded states. X-ray diffraction (XRD) and scanning electronic microscope (SEM) analyses showed that TiB2 particles were successfully produced in the matrix by the in situ reactions. The optimal content of TiB2 particles in the composites was 3 wt.%; moreover, the size of α-Al grains in the microstructure of the composites with 3 wt.% content was the smallest among the composites reinforced with different content of TiB2 particles, and the TiB2 particles showed a uniform distribution. The tensile strength and elongation of the composites (246 MPa and 9.8%, respectively) were 21.8% and 18.1% higher compared with those of the alloy matrix. When the TiB2 particle content was 5 wt.%, the cast composite exhibited the highest hardness of 113 HBW, which was 43.0% higher than that of the base alloy. Fracture analysis showed that the fracture mode changed from ductile to brittle as the mass fraction of TiB2in the composite increased. The mechanical properties of the 3 wt.% TiB2/2024 aluminum matrix composite were significantly improved after hot extrusion, with tensile strength and elongation values of 375 MPa and 19.7%, respectively, which were 52.4% and 101% higher than those of the as-cast material.

“…Kheirifard et al [10] rolled the A356 composites reinforced with Ni-P-coated bimodal ceramic particles and found that the agglomeration of SiC particles became separated, and the initial porosity in the AMCs was eliminated after rolling. Geng et al [11] reported that extruded in-situ TiB 2 /2024 AMCs showed significantly elongated grains along the extrusion direction, and that TiB 2 particle bands formed along the elongated grains. Xu et al [12] studied the evolution of hot-rolling texture in 6061Al/Al 18 B 4 O 33w aluminum alloy composites and found that the plate texture was composed of 2 1 2 f g 3 10 2 h i, 3 3 2 f g 1 1 3 h iand 1 2 2 f g 2 1 0 h i orientations after a 30 pct reduction, after which transformed to the fiber textures with 70 pct reduction.…”

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.
