Chemical designation | GJL-200 |
State | Gewaltbruch |
Etching | 3% Nital |
Cracking occurs preferentially along the graphite lamellae, which act as internal notches in the microstructure. In SEM images of the fracture surface, the structure of the graphite lamellae dominates, with overload fracture of the pearlitic matrix in between.
