“…Recent results obtained at 450 and 550 C in flowing LBE (2 m/ sec) with 10 À7 mass% O showed that austenitic steels undergo SBA (selective and non-selective leaching of material) since in-situ formed Cr-based oxide film is not a sufficient protective barrier [19]. The incubation time decreases from~500À4000 h to <200 h with increasing temperature from 450 to 550 C.…”

“…Liquid metal coolants, such as lead-bismuth eutectic (LBE) solutions, have many favorable qualities; however, it causes significant corrosion on common structural steels due to high dissolution rates [1][2][3][4][5]. To mitigate this corrosion phenomena, the dissolved oxygen content in the LBE may be limited by an intentional growth of a passivating oxide on the steel.…”

Evaluation of the Mechanical Properties of Naturally Grown Multilayered Oxides Formed on HCM12A Using Small Scale Mechanical Testing

The microstructure and mechanical integrity of protective multilayered oxide films grown in liquid metal on F/M steel HCM12A was investigated utilizing Raman spectroscopy, nanoindentation and micro-cantilever testing methods. The Raman spectra showed a Fe 3 O 4 outer layer and a Cr-rich spinel structure inner layer. The nanoindentation results showed a higher hardness value for the inner layer than for the outer layer. In addition, the hardness of the diffusion layer in between the inner layer and the bulk steel was measured. Quantitative fracture properties were obtained of the steel/oxide interface and within the oxide layers utilizing microcantilever testing. Furthermore the strength and elastic properties of the multilayered oxide film were measured and it was found that the porous structure in the inner Fe-Cr oxide limits the integrity of the steel/oxide interface.

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.
