Brittle Fracture of a Corroded Gray Cast Iron
M - Gray Cast ironP - CastingAp - EngineCd - Brittle Fracture
Cm - Fracture Surface AspectDf - Brittle Fracture
Aspect of the fracture surface of the 2" diameter casting. The fracture appeared flat, with secondary cracks, and the position of the fracture during the loading test is located in the region that was in tensile stress during the hot dip galvanized process (the part was sustaining its own weight during the zinc hot dip bath).
