摘要：
A mechanism is proposed whereby the elastic dipole distortion of stationary interstitial impurity atoms in lattice solution promotes nucleation and stabilization of double-kink-size screw dislocation segments on cross-slip planes. Stress relaxation accompanying interstitial-impurity-induced cross-slip can account for the experimental observations that small atom fractions of nitrogen in lattice solution in iron deformed at temperatures near 175°K decrease yield and flow stresses and increase ductility. © 1969.
