Developing a novel ODS steel to tailor mechanical properties and microstructure by co-adding VN and Y2O3 powders

open access: yesNuclear Materials and Energy
To enhance the high-temperature performance and extend the upper service temperature of oxide dispersion strengthened (ODS) steels for fusion reactor applications, a novel 9Cr-ODS steel was designed by co-adding 0.2 wt% VN and 0.35 wt% Y2O3 powders ...

Neutron Irradiation Brittleness of Structural Steels on Reactors

open access: yesJournal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan, 1964
As a recently results of the irradiation test, it has been found that the brittleductile transition temperature shifts to higher temperature for the structural steels when these are irradiated. Therefore, the problem of the brittle fracture of the reactor pressure vessel is now emphasized from the standpoint of the safety of reactor operation.This ...

BEHAVIOR OF ALUMINUM COATING BY CVD-FBR IN STEAM OXIDATION AT 700°C

open access: yesCT&F Ciencia, Tecnología & Futuro, 2014
Aluminum coatings have been obtained using the Chemical Vapor Deposition of Fluidized Bed Reactor technique (CVD-FBR), on austenitic stainless steels (AISI 304, AISI 316 and AISI 317), in order to evaluate resistance to steam oxidation at 700ºC.
