Abstract
The AISI 403 martensitic stainless steel is used as the end fitting ma terial in pressurised heavy water reactors. The fracture toughness of single quenched and tempered, double quenched and tempered, and Nb-mod ified variety of this steel has been evaluated at 473 and 573 K, Eleva ted temperature results are compared with the room temperature values reported in earlier studies. The double quenched and tempered and Nb-m odified structures show higher toughness and dJ/d alpha values at elev ated temperatures. (C) 1998 Elsevier Science B.V.
