... Abstract This article is an atlas of fractographs that covers pearlitic and ferritic ductile irons. The fractographs display the following: brittle cleavage fracture; fatigue crack propagation; fatigue and monotonic fracture surfaces; fracture modes in slow monotonic loading and impact loading...
