The focus of this investigation was to examine the influence of cryogenic processing on the mechanical properties and fracture toughness of Ductile Cast Iron.Ductile Iron has emerged as a major engineering material and are used in many structural applications.
In this investigation, compact tension and cylindrical tensile specimens were prepared from ductile cast iron as per ASTM standards and were processed by cryogenic heat treatment process. The mechanical properties and fracture toughness of these samples were evaluated and compared with non cryogenically treated samples. The influence of the cryogenic heat treatment on the microstructure of the samples was also examined. Test results show some significant improvements in fracture toughness in the cryogenically processed samples.
