Effects of matrix microstructure and particle distribution on fracture of an aluminum metal matrix composite

Development of Al-B-C Master Alloy Under External Fields

“…[21] A number of different approaches have been reported on the quantitative study of the reinforcement distribution in a composite such as the Dirichlet tessellation method, [22] the average inter-particle spacing or the mean free path, [23] the nearest and near neighbor distances, [24] the local area fraction, [24] and the radial distribution function. [21] This research has applied the widely accepted quadrat method for quantitatively analysis.…”

Advance on Al2O3Particulates Reinforced Aluminum Metal Matrix Composites (Al-MMCs) Manufactured by the Power Metallurgy(PM) Methods- Improved PM Techniques

“…It had been proved that alumina particlesc compounds could effectively improve the properties of Al-MMCs [7,[42][43]. In an Al-based composites reinforced with TiB 2 and Al 2 O 3 particulates, the yield strength of 545 MPa and tensile strength of 638 MPa were achieved, which were higher 9 and 6.8 times than that of pure Al.…”

“…There are a few reinforced materials, such as silicon carbide, aluminum oxide, the quasicrystalline phase, graphite, and so on [5][6][7][8][9][10][11] in the form of particles or whiskers that can be used for the reinforcement of Al-MMCs because of their improved physical and mechanical properties [3,7]. Among them, Al 2 O 3 are characterized by high stable, inert and thermal stability, which make it become one of the most popular reinforcement phases and have gained much attentions [3,6,8].…”

Flow stress of biomorphous metal–matrix composites

“…These mismatches can induce large stresses within the inclusions or at the matrix-inclusion interfaces [10,11]. A number of failure modes in MMCs have been reported in the past, including matrix/particle debonding [12][13][14][15][16], particle cracking [11,[17][18][19][20][21][22][23][24] and ductile failure in the matrix [25,26]. The elastic modulus, flow stress and ductility of MMCs are found to drop significantly as soon as such failures occur [27][28][29].…”
