“…The in situ formation of core–shell reinforcements has been realized by a number of methods, including solid state sintering of powder mixtures under pressure [ 11 , 12 , 13 , 14 ], solid state sintering under pressure followed by hot deformation processing [ 15 ] (a combination with pre-heating [ 16 ] or post-deformation annealing [ 9 ] is possible), sintering of previously obtained metal@metal core–shell particles with an additional amount of the powder of the matrix [ 21 ], a solid state reaction between metallic rods and the surrounding matrix [ 19 , 20 ], thixoforming [ 22 , 23 , 24 ], friction stir processing followed by annealing [ 25 ], modification of a pre-existing skeleton followed by infiltration [ 26 ], a reaction between solid particles with a metallic melt [ 27 ] and a synthesis in a metallic melt from the added reactants [ 18 ].…”

“…According to Guo et al [ 9 ], load transfer strengthening is the dominant mechanism of strength enhancement in Ti@Al 3 Ti core–shell particle-reinforced aluminum matrix composites. An advantage of Ti@Al 3 Ti core–shell particles over Al 3 Ti particles is that both the soft Al matrix and the Ti core hinder the propagation of cracks nucleated in the Al 3 Ti shell, which delays the fracture of the composite.…”

Shells forming in situ in the cases of metal (metal-containing) cores are of intermetallic or solid solution nature.…”

Metal matrix composites (MMCs) are a constantly developing class of materials. Simultaneously achieving a high strength and a high ductility is a challenging task in the design of MMCs. This article aims to highlight a recent trend: the development of MMCs reinforced with particles of core–shell structure. The core–shell particles can be synthesized in situ upon a partial transformation of metal (alloy) particles introduced into a metal matrix. MMCs containing core–shell particles with cores of different compositions (metallic, intermetallic, glassy alloy, high-entropy alloy, metal-ceramic) are currently studied. For metal core–intermetallic shell particle-reinforced composites, the property gain by the core–shell approach is strengthening achieved without a loss in ductility. The propagation of cracks formed in the brittle intermetallic shell is hindered by both the metal matrix and the metal core, which constitutes a key advantage of the metal core–intermetallic shell particles over monolithic particles of intermetallic compounds for reinforcing purposes. The challenges of making a direct comparison between the core–shell particle-reinforced MMCs and MMCs of other microstructures and future research directions are discussed.

Hybrid aluminum matrix composites reinforced with Fe-based metallic glass (FMG) and SiC particles were prepared using the spark plasma sintering (SPS) process, and the effect of matrix particle size on density, microstructure, and mechanical properties was investigated. The porosity content of the composites increased with increasing matrix particle size. Both reinforcing particles showed a more homogenous distribution in the matrix when smaller particles were used for the matrix of the composites. The phase properties and the stored dislocation density were not meaningfully affected by changing matrix particle size. The yield compressive strength and ductility of the composites decreased signi cantly with increasing particle size, so that the yield strength of the hybrid composite with a matrix particle size of 20 μm was about 80% higher than that of a similar composite with a matrix particle size of 63 μm.
