Cm - Fractography by SEMDf - Close to the External Surface
Fractography of the roller bearing, close to the external surface. In this position the fracture of the cylindrical roller bearing shows micromechanisms of decohesion at large carbides (cracked) and quasecleavage, typical of overloading this high strength tool steel (martensitic with carbides at 64 HRc).
