Phase development in As-cast, zirconium-based alloys containing type 304 stainless steel and Pu Conference Paper uri icon

abstract

  • Alloys comprising zirconium, Type 304 stainless steel (304SS), and Pu were cast in an induction furnace to investigate the effects of adding Pu to zirconium-stainless steel-based alloys. All alloys were cast at 1600 °C under flowing argon and ≈1 atmosphere pressure. As-cast ingots were sliced, polished, and examined by scanning electron microscopy-energy-dispersive spectroscopy analysis for microstructure and phase development. The development of phases and microstructure in Zr-304SS-Pu alloys is compared with available information for Zircaloy-2 and 4, and the effects of adding Pu to the Zr-304SS-based alloys is explored. Adding increasing levels of Pu to Zr-8 wt.% 304SS alloys does not drastically change the microstructure or phase development, but does increase the Pu solubility in the observed α-Zr phase, and does increase the Pu concentration at α-Zr lath boundaries. The α-Zr boundaries exhibit the highest Pu concentrations in the alloy.
