Industrially fabricated in-situ Al-AlN metal matrix composites (part B): The mechanical, creep, and thermal properties

Microstructural Characterization of In Situ Aluminum Matrix Composites with Interconnected Aluminum Nitride Produced by Arc Plasma-Induced Accelerated Volume Nitridation

“…The present and other Al/AlN composites exhibited CTE values lower than that based on the rule-of-mixture relationship, thus indicating strong interfacial cohesion between the matrix and reinforcement. In particular, the CTE of the present Al/AlN composite (20.1 × 10 −6 /K) was as low as that of nanocrystalline Al/AlN composites [15,16] and the CTE value was similar to that obtained using Turner's model [40], which assumes an equilibrium of internal stress between the particles and matrix.…”

“…Figure 9a shows the CTE of the Al/AlN and Al-12Si/AlN composites and those of various Al/AlN composites [13][14][15][16]. Owing to the low CTE of AlN compared with that of Al (4.0 and 23.6 × 10 −6 /K, respectively), the CTE decreased as V AlN increased in the Al/AlN composites.…”

“…Aluminum nitride (AlN) is a promising reinforcement for AMCs because of its low CTE, high TC, and thermodynamic compatibility with the Al matrix [13][14][15][16][17][18][19][20]. Various AMCs reinforced with AlN have been fabricated using ex situ processing techniques, such as stir casting [21] and pressure infiltration [22].…”

Evaluating the Corrosion Resistance of the Novel Al-Aln Metal Matrix Composites Produced Of Hot Direct Extrusion

“…Aluminium nitride (AlN) has garnered significant interest as an encouraging reinforcement within Al matrix composites. The properties of Al-AlN MMCs make them suitable for potential applications in the transportation and energy segments [1][2][3][4].…”

“…Developed extruded Al-AlN MMCs have excellent complex mechanical properties: high hardness, increased Young's modulus, and high tensile strength in combination with excellent creep and thermal conductivity indicators. Collectively, these attributes make them potential candidates for various load-bearing applications operating under elevated temperature conditions [2,3]. It should be noted all powders and techniques utilized are available.…”
