概要
- 論文の詳細を見る
From the assumption that the fluctuations of the local shear stress displaces a length of the dislocation for unit distance of the Peierls potential, the activation energy of Bordoni peak is derived for the crystals of relatively large Peierls stress and of low dislocation density. For the crystals of the contrary case, it is pointed out that the activation energy of Bordoni peak is affected by the dislocation density. The relations between the activation energies of Bordoni peak and Peierls stress are discussed on various crystals. The Peierls stress of LiF crystal, 10 kg/mm^2, is obtained.
