Chemical Interaction of Solute Atoms with Dislocations

概要

• 論文の詳細を見る

• A mechanism of interaction between a dislocation and solute atoms was discussed. It was shown to be reasonable to account for the difference in mechanical behaviours between face-centred and body-centred cubic crystals from the different locking mechanisms between these two types of crystals, the former being locked by a weaker but wider interaction range. while the latter being captured in a stronger and narrower valley of potential energy, the so-called Cottrell's atomosphere. The former results in a low critical shear stress which is almost independent of temperature and rate of strain. The latter gives rise to a very high critical shear stress at low temperatures, which, however, rapidly decreases with the rise of temperature.
