|---|---|
| Chemical designation | 42CrMo4 |
| State | former austenite grain boundaries |
| Etching | Bechet-Beaujard |
The micrographs show the former austenite grain boundaries etched after Bechet-Beaujard 30 min at 50 °C. After etching, the surface of the sample was polished with OPS for approx. 15-20 sec. Etching time and temperature may vary and depend on composition and heat treatment condition.
