Strain-induced structural evolution of interphase interfaces in CuZr-based metallic-glass composite reinforced by B2 crystalline phase

A Molecular Dynamics Study on the Defect Formation and Mechanical Behavior of Molybdenum Disulfide under Irradiation

“…The limited temporal and spatial scales make it challenging to trace these events experimentally. A feasible approach to address this concern involves employing molecular dynamics (MD) simulation, which enables researchers to comprehend material behavior at the atomic level and capture microstructure changes in femtosecond or even smaller units. − Currently, there are some studies focusing on the irradiation behavior of MoS 2 through MD simulations. For example, the interaction between MoS 2 and irradiated noble gas clusters was investigated by Ghaderzadeh et al using analytical potential MD simulations.…”

The innate interfacial elastic strain field of a transformable B2 precipitate embedded in an amorphous matrix

“…To solve the problem of the extreme brittleness of monolithic metallic glasses, one approach has been to add precipitates into the amorphous matrix to impede the propagation of shear bands, thereby delaying the fracture process and achieving better plasticity [1][2][3][4][5] . However, under tension loading, non-transformable precipitates embedded in an amorphous matrix usually lead to strain softening [6][7][8] , although phase transformable (shape-memory) inclusions in bulk metallic-glass composites (BMGCs) do display work hardenability ascribed to "transformation-induced" work hardening and plasticity [9][10][11][12][13][14][15][16][17] . Indeed, recent experimental studies reveal that shape memory BMGCs can display even higher strength [18][19][20] , ductility 18,19 , better work hardenability [18][19][20] and impact toughness 21 at cryogenic temperatures, which is ascribed to an enhanced transformed fraction of austenite precipitates (Supplementary Note 1).…”
