Abstract: Crystal structure and dislocation mode of high manganese cryogenic steel (43% Mn) are studied by using TEM. The research results proved that microstructure is austenite, grain boundaries has not particles, dislocation mode is tortuous lines, grain boundaries has dislocation pile up. The influence of dislocation pile up to intergranular fracture is discussed.

Key words: Cryogenic steel, Crystal structure, Dislocation, TEM
