• Abstract:
  This paper describes the forensic evaluations of three ; railroad rails containing electrode-induced pitting. These ; evaluations include: magnetic particle inspection to ; nondestructively detect cracks emanating from the pitting; ; fractography to study the fracture surfaces of the cracks; ; metallography to study the microstructure; analysis of chemical ; composition; and measurements of tensile mechanical ; properties and fracture toughness of rail steel. Moreover, the ; results of these evaluations confirm the hypothesis postulated ; by FRA that stray arcing during pressure electric welding can ; cause electrode-induced pitting.
