“…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.…”

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.

“…There are many processing methods to manufacture the Al-based MMNCs [7][8][9]. Among these methods, the Al-based MMNCs fabricated by in situ method exhibit more advantages in microstructure, such as clean particle-matrix interface, strong particle-matrix bonding, fine particles and economic viability [5,6,[10][11][12]. However, the reinforced nanoparticles tend to be clustered and agglomerated in the matrix due to their high specific surface energy.…”

In this paper, homogeneously dispersed TiC nanoparticles and fine-grained composite was successfully achieved by friction stir processing (FSP) of in situ 0.5 wt.% TiC/7085Al nanocomposites with different rotational speed. The effects of the rotational speed on the microstructures and tensile properties were investigated. Experimental results showed that the stir zone (SZ) exhibited equiaxed recrystallized grains with fine size and a high fraction of high-angle grain boundaries (HAGBs) caused by dynamic recrystallization (DRX). Moreover, the tensile strength and elongation of the friction stir processed (FSPed) composite were significantly improved compared with the base composite. With the rotational speed of 1000 rpm, the composite has the smallest grain size and the optimum mechanical properties. The average grain size decreased to 1.61 μm, the yield strength (YS), ultimate tensile strength (UTS) and elongation reached to 345 MPa, 429 MPa and 17.8%, respectively.

This article investigates in situ TiC particle‐reinforcement Al–Si–Fe matrix composites prepared by the contact reaction method. The addition of Ti–C to alloys results in the formation of β‐Fe and significantly refined the eutectic Si phase. Meanwhile, the exothermic reaction of C accelerates generation velocity of TiC. The refinement of the Al3Ti phase is attributed to refinement of α‐Al, which expedites solidification speed and prevents the further diffusion of Si atom, resulting in the bulk of the primary Si phase is formed locally. The best refinement effect of microstructure is obtained when the mixing powder addition content is 1.0 wt% and the Al‐12Si‐1Fe alloy has maximum tensile strength. The appearance of TiC is regarded as underlying reason for the re‐enhancement of mechanical properties.
