“…Up to now, there exist many different particle-reinforced ex-situ MGMCs, such as WC p / Zr-based [37][38][39], WC p / Cu-based [37], SiC p / Zr-based [37][38][39], SiC p / Cu-based [37,38], Ta p / Zr-based [37][38][39][40], TiB 2p / Mg-based [41], ZrC p / Zr-based [42], porous W / Zr-based [43,44], porous Mo / Mg-based [45,46], porous Ti / Mg-based [47], Ti p /Mg-based [48], porous SiC / Zr-based [49], Cu p / Cu-based [50], TiNb p /Zr-based [51], Ti p / La-based [52], and C p / Zr-based bulk MGMCs (the subscript, p, denoting particles) [53]. All these ex-situ dual-phase composites exhibit toughness at room temperature.…”

The mechanical properties of ex-situ and in-situ metallic glass matrix composites (MGMCs) have proven to be both scientifically unique and of potentially important for practical applications. However, the underlying deformation mechanisms remain to be studied. In this article, we review the development, fabrication, microstructures, and properties of MGMCs, including the room-temperature, cryogenic-temperature, and high-temperature mechanical properties upon quasi-static and dynamic loadings. In parallel, the deformation mechanisms are experimentally and theoretically explored. Moreover, the fatigue, corrosion, and wear behaviors of MGMCs are discussed. Finally, the potential applications and important unresolved issues are identified and discussed.

“…Unfortunately, monolithic MgZnCa bulk metallic glasses are quite brittle, limiting their further applications [2][3][4][5][6]. There have hitherto been a number of studies reporting on effective methods that enhance the strength as well as the plasticity of Mg-based BMGCs through the dispersion of ductile metallic particles such as those of Mo, Fe, Nb, and Ti [7][8][9][10][11][12][13][14][15][16][17]. These ductile metallic particles can absorb the shear strain energy of shear bands, confine the propagation of shear bands, and significantly improve their plasticity.…”

Rod samples of Mg 60 Zn 35 Ca 5 bulk metallic glass composites (BMGCs) dispersed with Ti particles have been successfully fabricated via injection casting. The glass forming ability (GFA) and the mechanical properties of these Mg-based BMGCs have been systematically investigated as a function of the volume fraction (V f ) of Ti particles. The results showed that the compressive ductility increased with V f . The mechanical performance of these BMGCs, with up to 5.4% compressive failure strain and 1187 MPa fracture strength at room temperature, can be obtained for the Mg-based BMGCs with 50 vol % Ti particles, suggesting that these dispersed Ti particles can absorb the energy of the crack propagations and can induce branches of the primary shear band into multiple secondary shear bands. It follows that further propagation of the shear band is blocked, enhancing the overall plasticity.

“…7(b). Improving fracture toughness by ∼50 MPa m 1/2 has been reported to occur upon the direct addition of 25 vol% porous Mo particles in a Mg 58 Cu 28.5 Gd 11 Ag 2.5 glassy matrix [20]. Mo particles acted as a hard phase to branch the primary shear band into multiple shear bands.…”
