Effects of characteristics of Mo dispersions on the plasticity of Mg-based bulk metallic glass composites

Development and microstructure optimization of Mg-based metallic glass matrix composites with in situ B2-NiTi dispersoids

“…(9) as: where A and B are both constants, indicating that there should be a linear relationship between log e p and 1/D. A similar linear relationship between fracture strain e and k À1/2 (where k is the inter-particle spacing) was also found by Jang et al [39]. The value of 1/D can be calculated from the data in Table 1, and log e p can be calculated from the data in Table 2.…”

Enhanced Mechanical Properties of MgZnCa Bulk Metallic Glass Composites with Ti-Particle Dispersion

“…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.…”

Homogeneous viscous flow behavior of a Cu–Zr based bulk metallic glass composites

“…However, seldom experimental results about the homogeneous flow behavior of BMGCs have been presented up to now, keeping in mind that it is the BMGCs consisting of secondary particles in the amorphous matrix always exhibit improved properties at room temperature [6,7]. In the previous investigations, Fu et al [8] found that rheological behavior of the Zr-Cu-Al BMGCs with various crystal volume fractions (v f ¼ 0-20%) can be explained in terms of the transition state theory, in which Newtonian behavior followed by a transition to non-Newtonian behavior.…”
