| 释义 | > as lemmasPeierls force  1.  Used attributively with reference to the resistance to the movement of a dislocation along a slip plane arising from the periodic nature of the crystal lattice, as  Peierls barrier,  Peierls force,  Peierls potential,  Peierls stress.The phenomenon was described by Peierls in  Proc. Physical Soc. (1940)  52 34–7. ΚΠ 1952    Adv. Physics 1 353  				The corresponding Peierls equation is satisfied by the displacements produced by an elastic dislocation a suitable distance ζ(D/b) below the plane. 1960    Proc. Royal Soc. A. 259 221  				Equation (8) refers to the increase in flow stress due to strain hardening above that due to impurities and Peierls force. 1969    Jrnl. Amer. Ceramic Soc. 52 1/1  				The rate-controlling deformation mechanism for polycrystals may be the thermally activated surmounting of the Peierls barrier. 1984    Science 9 Nov. 637/1  				Other factors that contribute to the low ductility of alloys with long-range order include restricted cross slip, high Peierls stress, [etc.]. 1999    Acta Materialia 47 2879  				Silicon crystals in the temperature domain where Peierls forces govern the dislocation mobility. 2001    Philos. Mag. A. 81 1257  				In silicon and other materials with a high Peierls potential, dislocation motion takes place by nucleation and propagation of kink pairs. 2003    Intermetallics 11 633  				Plastic deformation of this alloy at high temperature is controlled by a Peierls mechanism. 2003    Materials Sci. & Engin. A. 358 279  				Molybdenum disilicide..is a high Peierls stress material with a strong temperature dependence of the yield stress. < as lemmas |
