| Abstract: | The influence of
various nitrogen content on 77K impact toughness and the morphology of fracture of
austenitic steel Fe-38Mn melted by vacuum induction furnace were investigated. The results
show that the available nitrogen content can obviously improve the cryogenic impact
toughness of steel to modify the fracture morphology from intergranular fracture to
quasi-cleavage fracture. |
