Corrosion–erosion test of SS316L grain boundary engineering material (GBEM) in lead bismuth flowing loop

Environmental degradation of structural materials in liquid lead- and lead-bismuth eutectic-cooled reactors

“…To mitigate the GB penetration of liquid LBE in 316 AuSS due to erosion/corrosion, Saito et al [221] have tried the GB engineering method. The GB engineered material (GBEM) was produced by cold rolling and subsequent annealing of the base steel at 967 • C for 72 h. The cold rolling treatment introduced 3% pre-strain in the base steel and the produced GBEM showed 86% of its GBs to be CSL boundaries.…”

“…The magnified inset shows data acquired in the 500-600 • C range and corresponding to corrosion layer thicknesses between − 160 μm and 80 μm. Data collected from Refs [43,44,95,96,102,104,106,115,118,141,172,180,[187][188][189]191,[214][215][216][217][218][219][220][221][222][223][224][225][226][227][228][229][230]…”

Development of advanced materials for spallation neutron sources and radiation damage simulation based on multi-scale models

“…The corrosion resistance of the GBE controlled stainless steel has been tested against lead-bismuth eutectic used for target of the ADS system [28]. It was also found that optimized GBCD has a property strong to radiation damage through the helium ion Comparison of specimen surfaces of the HIPed compacts of (a) W-0.5TiC-Ar and (b) W-1.1TiC-Ar deformed at 1973 K and at 5 Â 10 À4 s À1 ; W-0.5TiC-Ar fractures at an elongation of 55%, whereas W-1.1TiC-Ar does not fracture even after exceeding 160% [17].…”

“…In the present work, the results of corrosion test on the austenitic steel SS316L-BM (base metal) and the SS316L-GBEM under flowing LBE condition have been performed using JAEA lead-bismuth flowing loop (JLBL-1) [28].…”

Effects of Crystal Orientation and Grain Boundary Inclination on Stress Distribution in Bicrystal Interface of Austenite Stainless Steel 316L

“…Researches have attributed the reason to the low boundary energies resulting in less impurity segregation, higher resistance to oxidation, and crack nucleation and propagation. Until recently, grain boundary engineering (GBE) studies for austenitic stainless steels have been performed to optimize the GBCD by improving the fraction of "special'' GBs and reducing the random boundaries [14][15][16][17][18][19]. e IGSCC of 316L stainless steels and nickel-based alloy 690 in supercritical water was considerably reduced by the GBE based on the GBCD control increasing fraction of LABs and 3 CSLBs [17].…”
