“…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.

“…The Al matrix composites with ceramic particles reinforcements show more excellent thermal stability, mechanical performance and wear resistance than the Al alloys [ 7 , 8 , 9 , 10 , 11 , 12 ]. The commonly used ceramic particle enhancers for Al matrix composites are TiC, TiB 2 , SiC, and B 4 C ceramic particles [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. The TiC particles showed low mismatch with Al matrix and obtained excellent Al-TiC interface bonding without the generation of interfacial reaction products [ 20 , 21 , 22 , 23 , 24 , 25 ].…”

The in situ TiC/Al-Cu nanocomposites were fabricated in the Al-Ti-C reaction systems with various carbon sources by the combined method of combustion synthesis, hot pressing, and hot extrusion. The carbon sources used in this paper were the pure C black, hybrid carbon source (50 wt.% C black + 50 wt.% CNTs) and pure CNTs. The average sizes of nano-TiC particles range from 67 nm to 239 nm. The TiC/Al-Cu nanocomposites fabricated by the hybrid carbon source showed more homogenously distributed nano-TiC particles, higher tensile strength and hardness, and better abrasive wear resistance than those of the nanocomposites fabricated by pure C black and pure CNTs. As the nano-TiC particles content increased, the tensile strength, hardness, and the abrasive wear resistance of the nanocomposites increased. The 30 vol.% TiC/Al-Cu nanocomposite fabricated by the hybrid carbon source showed the highest yield strength (531 MPa), tensile strength (656 MPa), hardness (331.2 HV), and the best abrasive wear resistance.

“…Nanoparticles tend to be pushed by the solidification front and therefore cluster at the grain boundaries in the casted NanoP-MMCs [12]. Although the plastic deformations such as hot extrusion [13] and rolling [14] have been utilized to optimize the microstructures of NanoP-MMCs, where the strains are not effective to disperse the clusters of nanoparticles. Thereafter, the severe plastic deformation (SPD) techniques which impose extremely high strains, including equal channel angular pressing [15], high pressure torsion [16], are employed and can neither uniform the nanoparticles completely.…”

Ceramic particles have been introduced into metal matrices to improve the strength and stiffness of metals, albeit at the cost of the ductility unfortunately. Simultaneously increasing the strength and ductility of metal matrix composites (MMCs) is still a challenge. Accumulative orthogonal extrusion process (AOEP), which disperses nanoparticles and refines grain structures of particles reinforced MMCs via severe plastic deformation, is proposed in this paper. The high strength (687 MPa) and superior ductility (14.8%) are simultaneously achieved in the resultant TiB 2 particles reinforced Al-Zn-Mg-Cu matrix composites, and the underlying mechanisms are discussed in terms of particles' influences. IMPACT STATEMENT An easily realized SPD technology is proposed to effectively optimize the structures of nanoparticles reinforced composites in industrial scale. High strength and good ductility are simultaneously achieved in the resultant composites.
