| Abstract: | This paper deals with the deformation and fracture of 5OCrV ferrite and carbide under tensile force. During tensile testing, voids uncleation is on the (C+F) matrix interfaces, ferrite and carbide. Then the primary voids will further grow and coarsen. Fur- ther improvement of these essential properties is still desirable and requires a fundamental understanding of the crack propagation process. |
