文摘
- •
The delamination fracture in bainitic magnetic yoke steel is a classic cleavage fracture.
- •
The phosphorus segregation band promotes the cleavage fracture in the delamination fracture surface.
- •
The increased texture intensity on the {001} easy cleavage face also increases the likelihood of cleavage fracture.
- •
The maximum stress concentration in thickness direction at ½ the thickness accelerates the occurrence of the crack.
