Abstract

Microhardness and SP tests were conducted to improve the reliability of ductile-brittle transition temperature (DBTT) shift evaluation caused by aging (thermal aging, neutron irradiation, cold rolling) using several model alloys (Fe-0.15C alloys and 2 1/4 Cr-1Mo steels). Although evaluation of DBTT by the SP test was overall good, intergranular brittleness could not be detected by SP DBTT measurement only. By combining other measurements like fractographic observation, however, material degradation can be evaluated more properly. (author).
