Mechanical properties and crystallization kinetics of Er-containing Cu–Zr–Al bulk metallic glasses with excellent glass forming ability

Comprehensive thermal analysis of a high stability Cu–Zr–Al bulk metallic glass subjected to high-pressure torsion

“…Heat flow/W g -1 corresponds to an extremely high GFA, slightly higher than was obtained for Cu 50 Zr 43 Al 7 BMG [47]. The extreme high value of ΔT x may indicate that the undercooled liquid has a very strong resistance against crystallization either by thermal activation or by plastic deformation and therefore any primary nanocrystallization is retarded.…”

Tuning isothermal crystallization kinetics by minor similar solute element substitution in novel La‐(AlGa)‐C metallic glasses

“…Metallic glasses (MGs) are expected to be a noteworthy type of novel alloy attributed to the amazing properties, including prominent mechanical properties of high strength, hardness and wear resistance, superior corrosion resistance, and good soft‐magnetic properties, which can be employed as an innovative model material for scientific investigations and engineering applications 1–5 . It is universally known that MGs will instinctively change to a relative state such as the crystalline counterparts for their metastable nature, and this process can be stimulated at elevated temperatures, which exhibits remarkable effects on the structures and properties of MGs 6–11 . Accordingly, persistent efforts are required for knowing the crystallization kinetics of MGs under diverse conditions, which is of considerable benefit to the glass‐forming ability (GFA), structures, and properties of the MGs and developing more amorphous‐crystalline composites with desirable structures and properties 6–18 .…”
