“…About 15 years ago, the renewal of the infrastructure at KIT for material tests in liquid metals was started, with special focus on liquid Pb and LBE as well as the controlled addition of oxygen to these liquid metals. From the exposure of material samples to static liquid metals and a flowing gas with a defined oxygen partial pressure in the test facility COSTA, over the erection of the liquid‐metal loop CORRIDA (Figure ) in which approximately 1 t of LBE circulates and is conditioned with respect to a defined oxygen concentration, the capacity for different types of material tests has been expanded to include creep and stress rupture in static liquid metals, flow‐assisted corrosion, and fretting (Table ). Using these facilities, various experimental campaigns were conducted.…”

Liquid metals appear to be attractive heat‐transport fluids, in particular if looking at their high thermal conductivities and low viscosities. Despite some pioneering technical applications in the past, complex handling, special requirements, safety concerns, and structural degradation of the materials have prevented their widespread application. However, progress in research and development on liquid‐metal science and technology has advanced considerably in the last decade, and this has opened the gate to their broader use in the short term. This requires a more differentiated view on liquid metals, particularly on the specific properties of individual fluids within the context of specific applications. By doing so, many commonly mentioned prejudices vanish or are of minor significance. At the Karlsruhe Institute of Technology, a comprehensive research program on liquid‐metal technology has been pursued for more than 50 years, and some of the advances in different applications will be outlined in this article.

Flowing liquid metal corrosion of structural steels in the Pb-Bi eutectic has been synthetically analyzed according to experimental results, mechanics model and aseptic technique. Foregone researches show that element of structural steels have a big influence on the corrosion of structural steels. The increase of temperature induces the increase of corrosion. High Cr steels, high Si steels and covered by the Al films on the steels can effectively defense the corrosion. Through building up the oxidation kinetics and corrosion-oxidation interactions model can be used to better analyze flowing liquid metal corrosion of structural steels in the Pb-Bi eutectic.

“…SiC ceramic was regarded as a candidate of the cooling pump impellers of accelerator-driven systems and Gen-IV lead-cooled fast reactors [1][2][3] due to its many excellent properties such as irradiation resistance, corrosion resistance, high-temperature strength, high-temperature creep resistance, oxidation resistance, and neutron transparency. [4][5][6][7][8][9] Although some scholars studied the compatibility of SiC bulk ceramics with LBE, 1,[10][11][12][13][14][15] there were no reports on the dynamic corrosion behavior of SiC impellers in the liquid lead-bismuth eutectic (LBE) alloy.…”

“…Back in 2005, Takahashi et al 10 found that SiC exhibited excellent corrosion resistance in flowing LBE at 550 • C. Subsequently, Rivai et al 11 evaluated the corrosion behavior of SiC ceramic after immersion in LBE by cross sectional observation and weight change analysis and found that SiC still exhibited high corrosion resistance and were compatible with LBE at 700 • C up to 1000 h. Kieser et al 12 reported that the composite SiSiC was entirely unaffected by the liquid lead under the erosion-corrosion attack with the test conditions of 600 • C, 4000 h, and 10 −8 wt% oxygen. Besides, the behaviors and flow velocity of the liquid lead were simulated for the first time with a computational fluid dynamics (CFD) code.…”

In order to determine the stress state and the specific dynamic corrosion behaviors of the cooling pump impeller in the liquid lead‐bismuth eutectic alloy (LBE), the numerical and the experimental investigations on the fast‐flowing LBE corrosion behaviors of the SiC impeller were conducted. The distributions of stress and displacement of the SiC impeller were simulated, and then the microstructure and mechanical properties of the corroded impeller were characterized. The results indicated that the SiC impeller met the strength requirement of 1000 rpm in LBE, and the dynamic LBE corrosion had little effect upon structure safety of the SiC impeller. The maximum stresses of the SiC impeller without and with LBE loading were .452 and 9.736 MPa, respectively. The maximum displacements of the SiC impeller without and with LBE loading were 76.385 and 4.096 μm, respectively. The LBE loading reduced the axial displacement of the impeller and acted as an impeller stabilizer to some extent. Blade elongating and flapping were the main vibration mode of the SiC impeller. The mechanical properties of the SiC impellers before and after corrosion were basically the same.
