“…In terms of the ductility of BMGCs, this property can be improved over their monolithic counterparts by modifying shear banding in the glassy matrix via incorporating a second phase of a certain shape, size and volume fraction into the metallic glass matrix. For example, Hays et al [27] have shown that the addition of a second phase in BMGs: (i) restricts shear band propagation; (ii) generates multiple shear bands; and (iii) creates additional fracture surface area.…”

“…[1] A major advantage of in situ BMGCs is that they potentially produce better interfacial bonding of the particle and matrix leading to superior mechanical properties. [1] There are at least three primary methods for producing in situ BMGCs (see e.g., [13][14][15][16][17][27][28][41][42][43][44][45][46][47][48][49][50] ):…”

“…[11][12][13][14] The easy nucleation and rapid propagation of shear bands can induce catastrophic fracture with very limited ductility, [15][16][17][18][19][20] impeding the further applications of BMGs. The fabrication of BMG matrix composites with ductile crystalline metal as reinforcement materials has yielded improvements in mechanical behavior [21][22][23][24][25][26][27][28] ; e.g., the in situ dendrite/BMG matrix composites exhibit increased both tensile and compressive strains to failure. [22][23][24][25][26][27][28] Previous studies [22][23][24] have pointed out that the ductile crystalline phase in the BMG matrix composite may have a dual role in the response of mechanical loading; they may serve as heterogeneous sites for the initiation of individual shear bands, while at the same time act as attraction or pinning centers during shear band propagation.…”

“…3,4 Such an enhancement of plasticity stems possibly from the formation of multiple shear bands initiated at the interface between the reinforcing agent and the metallic glass matrix, and their confinement in MGMCs. [5][6][7][8] From this point of view, recently, many researchers have investigated extensively the development of MGMCs mainly in Zr-based metallic glasses. 9,10 However, to extend the application fields of the BMGs, more attention should be drawn to the development of BMGs based on common metals such as Ni, Cu, Fe, and Ti.…”
