“…The average COF value of CMCs increased with the increase in the BNNS content, and the COF value of 0.8-CMC is close to that of P-Cu. According to previous studies [ 20 , 30 ], excessive nanosheets may reduce the properties of the composites.…”

Copper matrix composites (CMCs) were prepared by blending Cu particles with boron nitride nanosheets (BNNSs) and then by consolidating the blended particles using spark plasma sintering (SPS). The relative density of the compacts was over 99%, and an intact interface was formed between Cu and the BNNSs. Within the range of the BNNS content studied, its introduction improved microhardness and wear resistance. With the introduction of 0.2 vol% BNNSs, the friction coefficient reduced from 0.15 to merely 0.07, and the wear resistance improved by over 100%. This makes the CMCs reinforced with BNNSs promising materials in applications such as bearings.

“…When the size of the reinforcement particles reaches the nanoscale, they can improve the mechanical properties of HAMCs by reducing the stress concentration in the matrix and load transfer. However, ceramic nanoparticles easily agglomerate in the matrix and adversely affect the material properties because of their high surface energy and poor wettability with aluminum [24]. Therefore, the preparation of aluminum matrix composites with uniformly distributed nanoparticles is a significant challenge.…”

In this study, TiC-Al2O3/Al ribbons inoculant were prepared by mechanical alloying, spark plasma sintering (SPS) and melt spinning. Adding 5vol.% TiC-Al2O3/Al ribbons to an Al-Si-Mg-Ti (ASMT) alloy melt significantly refined the α-Al grains from 28.5 μm to 14.9 μm. In addition, the morphology of the eutectic silicon were modified and optimized, changing from needle-like silicon to spherical silicon. Adding the TiC-Al2O3/Al ribbons significantly improved the mechanical properties of TiC-Al2O3/Al-Si-Mg-Ti (TAASMT) alloy, including its elastic modulus (EM), yield strength (YS), ultimate tensile strength (UTS) hardness, and elongation which were increased by 5.4%, 18.4%, 32.7%, 8.3%, and 62.3%, respectively. These increases in the mechanical properties could be attributed to the intracrystalline reinforcement of the Al2O3 and TiC nanoparticles, well-bonded particle/matrix interface, modification of the eutectic silicon phases, and synergistic effects of the Orowan strengthening, Coefficient of thermal expansion (CTE) mismatch strengthening, load transfer, grain refining strengthening, and geometrically necessary dislocations (GND) strengthening.

“…After years of research, the preparation method of BNNSs has become mature, 18,22 and BNNSs have been more and more widely used. [23][24][25][26] However, at the moment, there is no similar report about the preparation of composite materials by incorporating BNNSs into AlN ceramics.…”

The boron nitride nanosheets (BNNSs)/aluminum nitride (AlN) composites were prepared by hot press sintering at 1600 • C. The microstructure, mechanical properties, and thermal conductivity of the samples were measured, and the effect of adding BNNSs to AlN ceramics on the properties was studied. It is found that the addition of BNNSs can effectively improve the mechanical properties of AlN. When the additional amount is 1 wt%, the bending strength of the sample reaches the maximum value of 456.6 MPa, which is 23.1% higher than that of the AlN sample without BNNSs. The fracture toughness of the sample is 4.47 MPa m 1/2 , a 68.7% improvement over the sample without BNNSs. The composites obtained in the experiment have brilliant mechanical properties.
