“…The hBN particles are not visible in the electron microscope images collected in this study. According to our previous experience, nanoparticles in nanocomposites prepared by ball milling are not uniformly distributed in the matrix, but remain mainly in the vicinity of grain boundaries [13,14]. Several strengthening mechanisms in NCs can be considered, including Orowan strengthening [15] grain boundary strengthening [16], and increased dislocation density due to large differences in the thermal expansion coefficient between the matrix and ceramic dispersoids (e.g., BN and Al2O3) [17].…”

Abstract. Aluminium-matrix-nanocomposites were manufactured by ball milling of microscale aluminium powder with BN nanoparticles in air, followed by subsequent consolidation by hot extrusion. The microstructure of the samples was studied using scanning electron microscopy. Vickers microhardness measurements were used to probe the mechanical properties of the samples. The amplitude dependent damping of the nanocomposites was measured at room temperature after thermal treatment of samples, and the linear thermal expansion was measured over a wide temperature range from room temperature up to 670K in the as-extruded state. The experimental results give a comprehensive picture of the behaviour of this nanocomposite system over the range of thermomechanical treatment conditions examined in this study. Based on these experimental data some possible influences of BN nanoparticles on the anelastic, plastic and thermal properties of microcrystalline aluminium are discussed.

“…hBN P is a good reinforcing material for MMCs because it makes them tougher and more self‐lubricating. [ 39 ] Squeeze, spray and stir casting, ultrasonic aided stir casting, powder metallurgy, and physical vapor deposition are all utilized in manufacturing the metal matrix composite. As compared to all other ways of production, ultrasonic aided stir casting seems to be the simplest and most cost‐effective way to make MMCs.…”

Magnesium (Mg) alloys are characterized by their high specific strength, strong damping resistance, and poor performance against corrosion. This study attempted to evaluate the corrosion capability and fatigue behavior of Mg–Zn alloys reinforced with nanosized silicon carbide (SiC) and hBN particles. Initially, different combinations (1.0 wt% nano‐SiCP [fixed] and 0.5, 1.0, and 1.5 wt% nano‐hBNP) of hybrid nanocomposites were synthesized through a stir‐ultrasonication casting process. The samples cut from the nanocomposites were subjected to salt spray, potentiodynamic polarization, tensile, and fatigue tests. The resistance to corrosion and fatigue characteristics of the monolithic alloy and hybrid nanocomposites were measured and compared. Due to the reduction in potential imbalance across the Mg‐α and I‐phases, the hybrid nanocomposites revealed enhanced corrosion performance as compared with the base alloy. The fatigue strength of the Mg–Zn alloy reinforced with 1% SiCP and 1.5% hBNP is about 94 MPa, which is 41% greater than the base alloy's fatigue strength. The scanning electron microscopy micrograph is helpful in investigating the microstructures of the corrosion, tensile, and fatigue‐tested samples.
