“…A similar fabrication and application of TiC nanoparticles was reported by Li and Tian et al [19,29] Without a further hot extrusion process, the as-synthesized TiC p is directly incorporated into Al and its alloys. A kind of master alloy has been fabricated by Li et al by combustion synthesis, which included 30 vol.% (nano-TiC + micron-Al 3 Ti) and 70 vol.% Al.…”

“…Other TiC particles which do not act as nuclei can effectively impede the solute diffusion, finally restricting the further growth of α-Al grains. Analogously, grain refinement has been extensively reported as realized using TiC particles [1,2,29,92,93,94]. In the study by Tian et al, bimodal-sized micron-TiC and nano-TiC particles exhibited excellent refinement and strength abilities.…”

“…Particularly, distinguished by a high hardness (28~35 GPa), high specific strength, high Young’s modulus (300~480 GPa), relatively low density (4.92 g/cm 3 ), high melting point (3067~3340 °C), high thermal conductivity, and low coefficient of thermal expansion (6.4 × 10 −6 /°C), as well as good wear and corrosion resistance, titanium carbides have shown splendid prospects. [2,14,15,16,19,21,29,30,31] In the past few years, many researchers have concentrated on exploring the relationship between the physical and chemical properties of titanium carbides and their sizes, morphologies, compositions and structures, which will shed new lights on the applications in various industries [7,8,9,10,11,12,13,14,15,16,17,18,22,23,24,25,26,27,28].…”

“…In the study by Tian et al, bimodal-sized micron-TiC and nano-TiC particles exhibited excellent refinement and strength abilities. The creep resistance of Al-Cu alloy has also been improved by the addition of TiC p [29]. The addition of nanosized TiC particles can effectively refine the θ ′ precipitates (Al 2 Cu) of Al-Cu, which was also favorable for improving the properties of the Al-Cu alloy [93].…”

It is widely known that the special performances and extensive applications of the nanoscale materials are determined by their as-synthesized structures, especially their growth sizes and morphologies. Hereinto, titanium carbides, which show brilliant comprehensive properties, have attracted considerable attention from researchers. How to give full play to their potentials in the light-weight manufacture, microwave absorption, electromagnetic protection, energy conversion and catalyst areas has been widely studied. In this summarized article, the synthesis methods and mechanisms, corresponding growth morphologies of titanium carbides and their further applications were briefly reviewed and analyzed according to their different morphological dimensions, including one-dimensional nanostructures, two-dimensional nanosheets and three-dimensional nanoparticles. It is believed that through the investigation of the crystal structures, synthesis methods, growth mechanisms, and morphology characterizations of those titanium carbides, new lights could be shed on the regulation and control of the ceramic phase specific morphologies to meet with their excellent properties and applications. In addition, the corresponding development prospects and challenges of titanium carbides with various growth morphologies were also summarized.

“…The superior Al-TiC interface provided good adhesion between the TiC particles and Al matrix, which contributed to decrease the thermal boundary resistance, resist the plastic deformation and increased the strength and hardness of the Al matrix [ 4 , 26 , 27 ]. It is necessary to mention that, the Al-Cu composites reinforced with nano-sized ceramic particles showed finer α-Al grains, higher tensile strength and ductility, higher creep resistance, and better sliding wear resistance than those of the composites reinforced with the micron-sized particles [ 7 , 28 , 29 ]. As reported, the in situ TiC/Al-Cu nanocomposites obtained simultaneous increases in tensile strength and ductility at high temperatures (ranging from 298 K to 573 K) compared to the Al-Cu matrix alloys [ 23 , 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.

Dependence of Creep Properties on Aging Treatment in Al–Cu–Mg Alloy

The mechanical properties are strongly associated with the heat treatment applied in the Al–Cu–Mg alloys. The peak aging treatment is normally employed following solution treatment to achieve a peak aging hardening effect. However, herein, it is shown that the creep resistance is improved at under‐aged (UA) conditions, where the material is transiently weaker than that at peak condition. Under the creep condition of 185 °C and 150 MPa, the creep fracture time of the UA (4 h) alloy is the longest at 146.5 h, followed by 128 h of the peak‐aged alloy and 72 h of the over‐aged alloy. The stress exponents are about 4, which indicates that the creep deformation mechanism of the alloy is mainly due to fracture caused by dislocation slip and grain boundary (GB) migration. Combined with the first‐principles calculation, the reason for the longer creep fracture time of the UA alloy is that the solutes Cu and Mg retained in the UA alloy interact with GBs and dislocations during creep.
