Unusual room temperature ductility of glassy copper–zirconium caused by nanoparticle dispersions that grow during shear

Formation of Ti–Zr–Cu–Ni–Sn–Si bulk metallic glasses with good plasticity

“…Glassy alloys tend to transform into more stable crystalline phases with supply of thermal energy or after plastic deformation [20,21]. Under compressive stress, the precipitation of nanocrystallites along shear bands [22,23] may result from high temperatures caused by the energy dissipation of shear deformation [17,24]. On the other hand, the Ti 45.8 Zr 6.2 Cu 39.9 Ni 5.1 Sn 2 Si 1 BMG has a very narrow supercooled liquid region of 35 K, indicating low stability of the supercooled liquid of this glassy alloy and easier precipitation of crystallites in the supercooled liquid state induced by localized temperature rising upon shear deformation.…”

Static and dynamic tight-binding simulations of the binary NbMo and CuZr alloys

“…In particular, the corrosion resistance of NbMo, CrTa and MoZr can be higher than that of the respective alloy constituting metals [1][2][3], while the mechanical properties of CuZr and NiNb are enhanced compared to their elemental counterparts [4][5][6][7][8]. In order to understand the origin of these changes a detailed knowledge of the electronic structures of these systems is required.…”

Simulation of Solidification Parameters during Zr Based Bulk Metallic Glass Matrix Composite’s (BMGMCs) Additive Manufacturing

“…The mechanism behind this is the formation and rapid movement of shear bands [26]- [33] in the volume of material by virtue of which material does not exhibit any yielding. In fact, they exhibit strain softening under tensile loading [34] [35] [36]. This renders them useless in practical structural engineering applications [37].…”
