| Abstract: | Under SEM and TEM,the relationship between quasicleavage crack and net dislocation at 77K of austenitic cryogenic steel 22Mn 13Cr 5Ni 0.25N was studied.The experimental results show that quasicleavage crack of this steel can be advanced by net dislocation which formed in low temperature crack. |
