Effect of tilt and twist angles on the cleavage crack propagation in ferritic steel
Source abstract
Abstract
The cleavage crack deviation at grain boundary has been studied in detail in a ferritic steel. The crystallographic orientations of the neighboring grains consisting cleavage facets have been obtained by Electron back-scattered diffraction analysis on the fracture surface. The possible tilt and twist angle between the cleavage facets have been predicted using the crystallographic orientations of the neighboring grains. Different geometrical features appear at the cleavage facet boundaries such as ridge zone and angular step have been co-related with the tilt and twist angle of the grain boundaries.
