Fabrication and characteristics of melt-spun Al ribbons reinforced with nano/micro-BN phases

Fabrication, characterization, and mechanical properties of spark plasma sintered Al–BN nanoparticle composites

“…BNNTs demonstrated excellent mechanical properties (ultimate tensile strength up to ~33 GPa [14]) comparable with those of CNTs, but they are more chemically and thermally stable [15]. Depending on the fabrication method, Al-BNNTs composites showed an increase in the tensile strength up to 150-300 MPa [16][17][18]. Though, it is particularly noted that the synthesis of a large amount of high quality BNNTs is still a challenge.…”

Annealing of ion-irradiated hexagonal boron nitride on Ir(111)

“…Hexagonal boron nitride is established as a key component in vertical van der Waals heterostructures [6][7][8]. Its high mechanical strength, low friction, excellent heat conductivity, resistance against degradation at high temperatures, and the ability to produce it as nanosheets or wires [9] moves its application for water cleaning [10], gas separation [11], and as a component in high-strength composite materials [12] into reach. Besides exfoliation, chemical vapor deposition on catalytically active metals is a way to prepare well-defined monolayers [13].…”

The quantitative relationship between microstructure and mechanical property of a melt spun Al–Mg alloy

“…The available experimental results reveal brittleness of amorphous ribbons [30][31][32], which limits their widespread applications. In contrast, the crystalline ribbons generally exhibit high strength and moderate ductility [23][24][25], rendering them a class of promising materials. Inspection of the published literature, however, indicates that few research efforts have been made to establish the quantitative relationship between microstructures and mechanical properties of melt spun crystalline ribbons, e.g., the quantitative contributions of various strengthening mechanisms associated with microstructural features to the overall strength, which hinders our ability to tailor the mechanical properties of the melt spun crystalline alloys by optimizing their microstructures.…”

“…Due to the lightweight attribute, melt spun Al alloys (both amorphous and crystalline) have been paid particular attention and extensive experimental studies have been conducted on this class of melt spun materials [10,12,16,[23][24][25][26][27][28][29][30][31][32], which involve characterization of microstructures and testing of mechanical properties. The available experimental results reveal brittleness of amorphous ribbons [30][31][32], which limits their widespread applications.…”
