Evolution of the dislocation microstructure during plastic deformation of austenitic-ferritic steel has been investigated using an in situ TEM straining experiment. It has been found that, at the beginning of plastic deformation, the lattice dislocations in austenite are activated first. The stress induced by the dislocation pile-up at the interphase boundary in austenite is accommodated by a slip transmission to ferrite. It has been appeared that the character of plastic deformation in ferrite due to the slip transmission through an interphase boundary depends on the austenite and ferrite orientation relationship.
