This article is an atlas of fractographs that helps in understanding the causes and mechanisms of fracture of maraging steels and in identifying and interpreting the morphology of fracture surfaces. The fractographs illustrate the tensile-test fracture, low-cycle fatigue fracture, fibrous fracture, crack-initiation zone, microvoid coalescence, fatigue-crack surface, hydrogen embrittlement, and fatigue striations of these steels.
