Segregation of impurity atoms to the strain fields of dislocations and the effective locking of the dislocations by the impurity atmospheres have been suggested earlier by others. The formation of interstitial atmospheres and their effect in iron was first treated mathematically by Cottrell and Bilby (Proc. Phys. Soc.; A62: 49(1949). Hirth and Lothe (Theory of Discolations, McGraw-Hill, New York (1968) reviewed more recent evidence of interstitial effects and theoretical treatments of interstitial dislocation interactions. This paper describes additional evidence of microsegregation of several interstitial elements in iron that were detected using secondary-ion mass spectroscopy (SIMS). 10 references, 2 figures.
