Effects of cooling rate on the glass formation process and the microstructural evolution of Silver mono-component metallic glass

Exploring the impact of cooling rates and pressure on fragility and structural transformations in iron monatomic metallic glasses: Insights from molecular dynamics simulations

“…Taking into account the effect of cooling rate, Figure S6 presents the variation in the percentages of the top five most populated Voronoi polyhedra (VPs) in Fe-MGs at 0 GPa under different cooling rates. Here, we find that there are no specific trends; each unit presents fluctuated values within a range of cooling rates, which is consistent with a previous study on Ni monoatomic glass [14]. Figure SM3 showcases the development of the bcc structure and crystal-like clusters within the iron system at room temperature while varying the pressure and quenching rates.…”

“…Recent studies have employed molecular dynamics (MD) simulations to investigate the influence of cooling rates on the structural evolution and formation of metallic glasses [14], as well as the effects of pressure on monoatomic metallic glasses [15,13]. In another investigation, researchers focused on a ternary bulk metallic alloy, namely the Zr 60 Cu 20 Fe 20 alloy, studying its atomic structures and the glass formation process using molecular dynamics simulations with many-body tight-binding potentials.…”

“…Figure 3: RDFs for monatomic iron at 300 K under various quenching conditions of pressure: (a) for the cooling rate of 5 × 10 12 , (b) for the cooling rate of 1 × 10 13 , (c) for the cooling rate of 5 × 10 13 , (d) for the cooling rate of 1×1014 . Note that the first peak represents the interatomic distance between the central atom and its neighbors, and the distinct splitting of a broad second peak and the appearance of a shoulder close to the second peak is a signature of crystalline formation.…”

Influence of chromium addition and cooling rate on Kinetic and microstructural evolution in FexCr100-x Metallic Glasses

“…In Figure 1(b); the graphs highlight a significant positive correlation between the cooling rate and the increase in the glass transition temperature (T g ) value. This observed linear extrapolation phenomenon is a consequence of the limited duration of rapid cooling, impeding atoms from undergoing sufficient rearrangement to form a well-organized crystalline structure [13,14]. Importantly, this extrapolation finding suggests that the trend applies to other cooling rates as well.…”

“…Metallic glasses, or amorphous materials, are structures lacking a crystalline arrangement, formed when the crystallization process is obstructed. These materials have made remarkable strides, chiefly owing to their exceptional mechanical properties, notably high fracture strength and significant elastic deformation, which setthem apart from crystalline materials [1]. Amorphous alloys have garnered noteworthy attention as potential biomaterials due to their advantageous trait of resisting corrosion across various forms [2].…”
