Twin forming reason in carburized layer of 1Cr11Ni2W2MoV steel and its effect on the mechanical properties were investigated with microstructure observation,fracture examination,micro hardness test and EDS analysis. The results show that the twin forming reason is related with the lower carbon potential and higher carburizing temperature. The twin existing in carburized layer changes the fracture mode and results in the brittleness increase, and it should be regarded as defect in carburized layer of 1Cr11Ni2W2MoV steel.
