Formation of a Satellite Phase in the Neutron Irradiated Reactor Steel

Abstract

A hexagonal satellite phase could be identified, in addition to the body-centered-cubic (bcc) iron, by X-ray powder diffraction method (CoKα, radiation) in a reactor steel after neutron irradiation and tensile testing. The hexagonal satellite phase is metastable, its diffraction pattern disap­pears from the X-ray record at room temperature after 1.5–2 months of re­laxation. The structure of the satellite phase is closely related to the structure of the hexagonal high pressure polymorph ε-Fe. The presence of the satellite phase enhances the toughness of irradiated steel during tensile tests at room temperature.
