A STUDY ON THE MICROSTRUCTURE AND FRACTURE PROCESS OF A PEARLITIC STEEL BY MEANS OF EDC TECHNIQUE

An investigation of the microstructure and the mioroprocess of fracture of an eutectoid pearlitic steel has been carried out by means of electron-diffraction-contrast(EDC) and other analytical techniques. The nature of the dislocations in pro-eutectoid-ferrite and ferrite in pearlite was determined. The character of interface conjunction between ferrite and cementite was discussed. The fracture process of pearlitic steel has been analysed crystallographically.
