Abstract

Liquid lead–bismuth eutectic (LBE) can serve as a heat transfer fluid for advanced nuclear applications as well as concentrated solar power but poses corrosion challenges for the structural materials at elevated temperatures. Oxide passivation of the surfaces of these materials during exposure to liquid LBE can inhibit such material degradation. In this study, transmission electron microscopy of oxides formed on Fe-Cr-Al alloy during exposure to lowoxygenated LBE at 800C has been performed. A complex structure of the oxide film has been revealed, consisting of a homogeneous inner layer of mostly Al₂O₃ and a heterogeneous outer layer.

A study of the effects of minor additives to Pb-Bi eutectic: Designing novel Pb-Bi-X liquid alloys for heat transfer applications

Journal Article Popović, M. P. ; Olmsted, D. L. ; Bolind, A. M. ; ... - Materials & Design

Lead-bismuth eutectic (LBE) is a promising heat transfer fluid candidate for fast-neutron nuclear reactors and for concentrating solar power systems, due to its low melting point and advantageous thermophysical properties, but suffers from causing liquid-metal corrosion in many solids used as structural materials. Adding a suitable element to LBE to form a ternary alloy, along with proper oxygen concentration in LBE at desired temperature, might provide a formation of the protective intermetallic layers besides the formation of protective oxides on the solid surface. In this study, novel Pb-Bi-X alloys, as improvement LBE, have been designed for a broad temperature range,more »« less

Oxidative passivation of Fe–Cr–Al steels in lead-bismuth eutectic under oxygen-controlled static conditions at 700° and 800 °C

Journal Article Popovic, M. P. ; Bolind, A. M. ; Aussat, Y. ; ... - Journal of Nuclear Materials

Lead-bismuth eutectic (LBE) is a candidate heat transfer fluid for fast nuclear reactors and for concentrating solar power energy systems, due to its low melting point and beneficial thermophysical properties. Increasing the maximum operating temperature beyond 600 °C, can increase thermal efficiency of power conversion. However, LBE causes liquid-metal corrosion in many solids used as structural materials at high temperatures, due to increasing solubility of their constituents. A way to mitigate this issue is to establish a controlled oxidative passivation, by maintaining a desirable oxygen concentration in liquid LBE to promote formation of protective oxide scales on structural materials.

A study of deformation and strain induced in bulk by the oxide layers formation on a Fe-Cr-Al alloy in high-temperature liquid Pb-Bi eutectic

Journal Article Popovic, M. P. ; Chen, K. ; Shen, H. ; ... - Acta Materialia

At elevated temperatures, heavy liquid metals and their alloys are known to create a highly corrosive environment that causes irreversible degradation of most iron-based materials. In this paper, it has been found that an appropriate concentration of oxygen in the liquid alloy can significantly reduce this issue by creating a passivating oxide scale that controls diffusion, especially if Al is present in Fe-based materials (by Al-oxide formation). However, the increase of the temperature and of oxygen content in liquid phase leads to the increase of oxygen diffusion into bulk, and to promotion of the internal Al oxidation. This can causemore »« less

High operating temperature heat transfer fluids for solar thermal power generation. Final report

Technical Report Hosemann, Peter ; Asta, Mark ; Schroers, Jan ; ...

This is the final technical report for the DOE MURI project on developing high-operating temperature heat transfer fluids for solar thermal power generation. This project aimed to evaluate liquid metals as a heat-transport fluid and potential energy storage medium for concentrated solar powered (CSP) systems. The project consisted of five phases, starting with fluid selection and screen and ending with potential CSP integration. The initial fluid selection arrived at heavy liquid metals as candidate fluids such as lead bismuth eutectic (LBE) as the prime liquid-alloy candidate to be studied, given the conditions above. Fifty-seven liquid compositions were initially identified withmore »« less

The Development and Production of a Functionally Graded Composite for Pb-Bi Service

Technical Report Ballinger, Ronald G

A material that resists lead-bismuth eutectic (LBE) attack and retains its strength at 700°C would be an enabling technology for LBE-cooled reactors. No single alloy currently exists that can economically meet the required performance criteria of high strength and corrosion resistance. A Functionally Graded Composite (FGC) was developed with layers engineered to perform these functions. F91 was chosen as the structural layer of the composite for its strength and radiation resistance. Fe-12Cr-2Si, an alloy developed from previous work in the Fe-Cr-Si system, was chosen as the corrosion-resistant cladding layer because of its chemical similarity to F91 and its superior corrosionmore »« less
