Collective Motion of Atoms in Metals by First Principles Calculations
Fundamental information on the collective motion of atoms can be learned by tracing imaginary phonon modes in deformed crystals. This should be useful to investigate the atomic process of plaston in a logical man...

Chapter
Plaston—Elemental Deformation Process Involving Cooperative Atom Motion
The concept of ‘plaston’ that involves cooperative atom motion under shear stress is discussed as a deformation carrier that nucleates and moves in the deformation front under shear stress in many different ma...

Free-energy-based Atomistic Study of Nucleation Kinetics and Thermodynamics of Defects in Metals; Plastic Strain Carrier “Plaston”
Plastic deformation proceeds through the nucleation and migration of localized atomistic defects, i.e., plastons (e.g., dislocations, disconnections, disclinations, and shear transformation zones), as plastic ...

Proposing the Concept of Plaston and Strategy to Manage Both High Strength and Large Ductility in Advanced Structural Materials, on the Basis of Unique Mechanical Properties of Bulk Nanostructured Metals
Advanced structural materials are required to show both high strength and large ductility/toughness, but we have not yet acquired the guiding principle for that. The bulk nanostructured metals are polycrystall...

Chapter
Atomistic Study of Disclinations in Nanostructured Metals
Disclination is a line defect in which rotational symmetry is broken. Recently, such defects have been observed in nanostructured metals. Hence, disclinations can bring out the unique properties of nanostructu...
