WebDuctile (also called Nodular and Speroidal Graphite) Iron is stronger than gray iron, is tougher and is much less expensive to cast complex parts than steel forming. The iron microstructure is characterized by the “Nodularity” (roundness) quality, nodule size and nodule density (nodules per mm²). WebObjective: Graphite components in a Very High Temperature Reactor (VHTR) may fracture under the actions of external and internal (irradiation-induced) stresses. Measurement of the fracture properties of graphite is therefore essential in the design and structural integrity assessment of VHTR cores.
