“…The liquid composition within the spinodal region may decompose into two liquid phases assigned as Ni-rich liquid and Curich liquid and form the two-liquid metallic glass. The designed alloy composition is selected, namely, Zr 65 [24]. During the alloy design for optimum BMGs, the GFA index was also part of the study.…”

“…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.

“…Ma et al in 2003 [2]. Since then, many other types of Mg-based BMGCs have been developed with ceramic and metallic particles (e.g., TiB 2 [15], ZrO 2 [16], WC [17], SiC [18], and Nb [19], porous Mo [20], Ti [21], and Fe [22]) and all exhibits remarkable plasticity improvement. Among these developed Mg-based BMGCs, the Mg 65 Cu 25 Gd 10 /40 vol.% Ti BMGC displays the highest plastic strain of 41% [21].…”
