“…In our previous work, nano-sized TiC particles of 40–100 nm were prepared by using carbon nano tube (CNTs) with the finer size and higher chemical activity as the carbon source [ 26 , 27 ], and micro-sized TiC particles were fabricated by using C black as carbon source [ 16 , 28 ]. When CNTs and C-black were used, the synthesized TiCx with particles sizes of 0.08–1 and 0.9–5 μm, respectively, was spherical or nearly spherical in shape.…”

Bimodal hybrid in-situ nano-/micro-size TiC/Al composites were prepared with combustion synthesis of Al-Ti-C system and hot press consolidation. Attempt was made to obtain in-situ bimodal-size TiC particle reinforced dense Al matrix composites by using different carbon sources in the reaction process of hot pressing forming. Microstructure showed that the obtained composites exhibited reasonable bimodal-sized TiC distribution in the matrix and low porosity. With the increasing of the carbon nano tube (CNT) content from 0 to 100 wt. %, the average size of the TiC particles decreases and the compressive strength of the composite increase; while the fracture strain increases first and then decreases. The compressive properties of the bimodal-sized TiC/Al composites, especially the bimodal-sized composite synthesized by Al-Ti-C with 50 wt. % CNTs as carbon source, were improved compared with the composites reinforced with single sized TiC. The strengthening mechanism of the in-situ bimodal-sized particle reinforced aluminum matrix composites was revealed.

“…Nie et al [22] found that the addition of Ni into the Al-Ti-C system can effectively inhibit the growth of {100} surfaces and successfully prepared cube-shaped TiC x particles. Wang et al [23] fabricated 40-60 vol% TiC x /Al composites by using C-black as the carbon source in the Al-Ti-C system. They found that the main morphologies of the reinforcing particles were sphere and close-to-sphere.…”

Shape-Controlled TiCx Particles Fabricated by Combustion Synthesis in the Cu-Ti-C System

TiC x particle-reinforced Cu-matrix composites were prepared in the Cu-TiC system by thermal explosion and hot press. Extracted TiC x particles with various shapes of in situ TiC x particles in the Cu-TiC system were observed through the Field Emission Scanning Electron Microscope (FESEM). It was found that octahedral and close-to-spherical, spherical or cubic TiC x could be fabricated by changing the C/Ti molar ratio and Cu content. Then, the effect of the C/Ti molar ratio and constituent element concentrations on the shape of in situ TiC x particles was determined: the shape of TiC x particles is octahedral at a C/Ti ratio of 0.4-0.6 with the presence of 70 vol% Cu; or spherical and close-to-spherical at 0.8-1.0 with the presence of 70 vol% Cu; or cubic at C/Ti ratios ≥1.0 with the presence of Cu from 80 vol%-90 vol% and even at C/Ti ratios >1.0 with the presence of 70 vol% Cu. The shape-controlled synthesis of TiC x particles in the Cu-TiC system is realized.

“…Yu et al [ 30 ] proposed that the smaller size of primary Mg 2 Si could improve the ultimate tensile strength of magnesium alloy. Wang et al [ 31 ] fabricated various volume fraction TiC x /Al composites with different particle sizes. They found that high volume fraction TiC x /Al composites had higher compression strength, while where was no research concerning the effect of TiC x size on the property of in-situ TiC x /metal composites.…”

The compression properties and electrical conductivity of in-situ 20 vol.% nano-sized TiCx/Cu composites fabricated via combustion synthesis and hot press in Cu-Ti-CNTs system at various particles size and morphology were investigated. Cubic-TiCx/Cu composite had higher ultimate compression strength (σUCS), yield strength (σ0.2), and electric conductivity, compared with those of spherical-TiCx/Cu composite. The σUCS, σ0.2, and electrical conductivity of cubic-TiCx/Cu composite increased by 4.37%, 20.7%, and 17.8% compared with those of spherical-TiCx/Cu composite (526 MPa, 183 MPa, and 55.6% International Annealed Copper Standard, IACS). Spherical-TiCx/Cu composite with average particle size of ~94 nm exhibited higher ultimate compression strength, yield strength, and electrical conductivity compared with those of spherical-TiCx/Cu composite with 46 nm in size. The σUCS, σ0.2, and electrical conductivity of spherical-TiCx/Cu composite with average size of ~94 nm in size increased by 17.8%, 33.9%, and 62.5% compared with those of spherical-TiCx/Cu composite (417 MPa, 121 MPa, and 40.3% IACS) with particle size of 49 nm, respectively. Cubic-shaped TiCx particles with sharp corners and edges led to stress/strain localization, which enhanced the compression strength of the composites. The agglomeration of spherical-TiCx particles with small size led to the compression strength reduction of the composites.
