OBSERVATION OF FRACTURE SURFACES OF TRC TEST SPECIMENS WITH SCANNING ELECTRON MICROSCOPE

Delayed cracking sensitivity of some kinds of high strength steels was evaluated by the TRC test and the fracturre surfaces of specimens, which had root cracking, were observed by scanning electron microscope. The relation was investigated between the tensile restraint stress (=applied stress), the quasi-cleavage fracture area and rupture time.
