Crystal forming ability of amorphous refractory metals under nanoindentation: a molecular dynamics study
Prashant Dwivedi, Alberto Fraile, Tomas Polcar
Amorphous refractory metal coatings combine high hardness with chemical inertness, yet their metastability makes them prone to mechanically induced crystallisation (devitrification…

Effect of crystallinity on the frictional and wear performance of molybdenum disulfide: A molecular dynamics study
Abhiram B R, Ilia Ponomarev, Tomas Polcar
The frictional and wear performance of molybdenum disulfide (MoS2) is significantly influenced by its intrinsic arrangement of crystals or crystallinity. In this study, we investig…
