摘要

The absence of tetragonality in low carbon ferrous martensites was explained by Speich in terms of the redistributions of carbon atoms to lattice defects such as dislocations. However, until recently no experimental techniques were available to measure carbon atom distribution directly. Atom probe microanalysis has now been used to demonstrate unequivocally that carbon atom segregation to dislocations occurs in these microstructures. Observations of so-called 'Cottrell atmospheres' surrounding dislocations in low carbon martensites are presented. The interpretation of these results is discussed in terms of the theory of dislocation-solute interactions.
