ML00131 — Brittle Failure of a Soft Roller BearingM - Wear Resistant SteelP - Roller BearingAp - Mechanical IndustryCd - Heat Treatment Defect
Martensitic structure close to the external diameter of the cylindrical roller bearing, in the circuferemtial direction, presenting large carbides (not aligned due to the direction of the section) and a martensitic matrix. in this region the fracture presented quasecleavage micromechanism as well as decohesion of large carbides.
