Seven FeCrAlY-Al2O3 nanoceramic composite coatings are deposited on F/M steel via plasma spraying and laser remelting. A systematic investigation is conducted to examine the dependence of microstructure, mechanical properties, lead–bismuth eutectic (LBE) corrosion resistance nano-Al2O3 addition different Cr Al contents. With increase in content FeCrAlY, gradual refinement coating grains occurs. The promotes elemental segregation precipitation second phase. notably enhances properties that...
Aiming to newly-developed FeCrAl alloys for accident-tolerant fuels (ATF) in light water reactors (LWR), an in-situ investigation of scan transmission electron microscopy (STEM) observation and annealing was performed order understand the evolution radiation-induced defects (RID) Cr segregation during elevating temperature. In this study, were irradiated with 6Mev Au+ ions up a dose 10 dpa at 400°C, RID depth 1μm assess by TEM annealing. A layer, dislocation loop raft Cr-decorated loops...
The structural evolution of Cr-coated Zr-4 after irradiation was studied via in situ TEM the temperature range from room to 1000 °C. results show that krypton bubbles appeared at ~700 °C, and their size increased with increasing temperatures. grain shape irradiated substrate changed temperature, finally, columnar crystals appeared, which related compressive stress induced irradiation. Cr2Zr C14 phases formed both interface 700 °C Moreover, accelerated failure process Cr coating high...
Microstructure, mechanical properties, corrosion resistance and high-temperature oxidation of four CrSi coatings with different Si content ranging from 0 at% to 67 were investigated. With increasing 11 at%, the main forms exist are Cr3Si, Cr5Si3 CrSi2, respectively. All own higher nano-hardness due formation intermetallic. For ≤33 show good in static pure water high temperature pressure. However, (67 at%) leads dissolution form [Si(OH)]4, as well insufficient Cr continuous Cr2O3 layer. The...
