This article is an atlas of fractographs that helps in understanding the causes and mechanisms of fracture of tool steels and in identifying and interpreting the morphology of fracture surfaces. The fractographs illustrate the low-cycle and high-cycle fatigue fractures, tension-overload fractures, impact fractures, microstructure, quench cracking, brittle-in-service failure, hydrogen embrittlement, stress-corrosion cracking, and grain-boundary cracking of tool steel components. These components include diesel engine injector plungers, rivet-heading tools, circular saw blades, and open-header dies.
