The Effect of Strain Rate on the Deformation Processes of NC Gold with Small Grain Size
Crystals, 2020 The strength of nanocrystalline (NC) metal has been found to be sensitive to strain rate. Here, by molecular dynamics simulation, we explore the strain rate effects on apparent Young’s modulus, flow stress and grain growth of NC gold with small size. The

Grain charging in protoplanetary discs [PDF]
, 2011 Recent work identified a growth barrier for dust coagulation that originates in the electric repulsion between colliding particles. Depending on its charge state, dust material may have the potential to control key processes towards planet formation such

Influence of Hot Forging Parameters on a Low Carbon Continuous Cooling Bainitic Steel Microstructure
Metals, 2020 Thermomechanical processing of low carbon bainitic steels is used to obtain a bainitic microstructure with good strength and toughness by continuous cooling after forging without the need of further heat treating, hence reducing manufacturing costs ...

Grain growth and grain translation in crystals [PDF]
Acta Materialia, 2016 Grain growth is generally driven to minimize the overall grain boundary energy. However, for low-angle grain boundaries the requirement that lattice planes be continuous across the boundary gives rise to a coupling between the normal motion of the grain boundary and the tangential motion of the lattice.

Journal of Mechanical Engineering and Sciences, 2020 The grain growth of an ultrafine-grained iron-chromium alloy has been investigated focusing on the early stage of restoration of strain. Ultrafine-grained (UFG) material has been prepared by equal channel angular pressing (ECAP) up to eight passes via ...
