Abstract
Fracture is the ultimate continuum of a material. Hence, it is possible that the fracture features contain the signature of the whole deformation process undergone due to variation in triaxial state of stress under tensile deformation. The two dimensional fracture features were correlated with the stress triaxiality ratio where initial inclusion content was unaltered. In order to test that, many tensile experiments of a superalloy were carried out at different notch geometries and fractographic investigation was done extensively to correlate the fracture features (ie., fractured grain size, extent of tearing ridge, dimple diameter and dimple number density) with the tensile properties.
