Corrosion characteristics of reduced activation ferritic-martensitic steel EUROFER by Li2TiO3 with excess Li

Nuclear Materials and Energy, 2018
In a solid breeding blanket, ceramic breeder pebbles are in contact with reduced activation ferritic martensitic (RAFM) steel at high temperatures for years and accordingly form a corrosion layer on the blanket structural steel.

PLEPS study of ions implanted RAFM steels

Journal of Physics: Conference Series, 2014
Current nuclear power plants (NPP) require radiation, heat and mechanical resistance of their structural materials with the ability to stay operational during NPP planned lifetime. Radiation damage much higher, than in the current NPP, is expected in new generations of nuclear power plants, such as Generation IV and fusion reactors.

Modeling of Ductile Tearing for RAFM Steel Eurofer97

Procedia Materials Science, 2014
AbstractThe contribution describes experiments and numerical modelling performed to deal with ductile tearing for RAFM steel Eurofer97. Based on results of tensile testing and results of FEA a micromechanical model of ductile fracture Gurson-Tvergaard-Needleman (GTN) was calibrated. This model was then applied for simulation of measured J-R curve.

Numerical Simulation on Thermodynamics Performance in the Fireproof Sealing by Finite Element Analysis

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
In this paper, the finite element analysis was firstly employed to investigate the thermal analysis on two fireproof sealing models with ANSYS software under HC standard temperature‐time condition. The main thermal parameters were analyzed and obtained, including temperature field, thermal flux, and thermal gradient.
