207 アモルファス金属の力学特性と結晶化挙動に与える変形履歴の影響の分子動力学解析 [in Japanese] Molecular Dynamics Study on Influence of Deformation History on Mechanical Property and Crystallization Behavior in Amorphous Metal [in Japanese]
Access this Article
This paper shows the deformation effects on the mechanical property and crystallization behavior in amorphous metal by molecular dynamics (MD) simulations. The Finnis-Sinclair potential for Fe is assumed as interatomic potential. At first, MD simulations of cyclic loading for the model amorphous are performed to obtain severely deformed materials. Then reloading and crystallization simulations are performed. The maximum stress and strain-stress relation within the elastic range are much influenced by deformation history, but the crystallization behavior does not depend on it so far.
