摘要

传统的高铬铁素体/马氏体钢，如T91和AISI 316 L，以及新的氧化物分散强化(ODS)钢，即具有良好Y2O3分散的Fe-Cr(铁素体或马氏体)，是在侵蚀环境中应用的有前途的结构材料。为了提高液态铅作为冷却剂的液态金属快堆(LMFR)结构材料的效率和寿命，目前研究的重点是液态铅/钢界面上发生的界面现象。更好地了解界面现象是选择满足苛刻应用要求的结构材料的关键问题。本文对液态铅在550 ~ 820℃和不同含氧气氛下与T91、AISI 316L、ODS- 12Cr和ODS- 14cr钢接触时的润湿特性和界面现象进行了基础研究。

Wetting property of liquid Pb on different steel candidates as structural materials for the Generation IV nuclear reactors

Conventional high-chromium ferritic / martensitic steels, such as T91 and AISI 316 L as well as the new oxide dispersed strengthened (ODS) steels, i.e. Fe-Cr (ferritic or martensitic) with a fine Y2O3 dispersion, are promising candidates as structural materials for applications in aggressive environments. In order to improve the efficiency and lifetime of structural materials for liquid metal fast reactor (LMFR), where liquid lead (Pb) is used as coolant, the investigations are currently focused on the interfacial phenomena occurring at the liquid Pb/steel interfaces. The better understanding of the interfacial phenomena is the key issue for the selection of structural materials meeting the requirements of the demanding application. In the present work, a fundamental study on the wetting characteristics and the interfacial phenomena of liquid Pb in contact with T91, AISI 316L, ODS- 12Cr and ODS-14Cr steels over the temperature range 550�820�C and under different oxygen containing atmospheres is reported.

期刊介绍： High Temperatures – High Pressures (HTHP) is an international journal publishing original peer-reviewed papers devoted to experimental and theoretical studies on thermophysical properties of matter, as well as experimental and modelling solutions for applications where control of thermophysical properties is critical, e.g. additive manufacturing. These studies deal with thermodynamic, thermal, and mechanical behaviour of materials, including transport and radiative properties. The journal provides a platform for disseminating knowledge of thermophysical properties, their measurement, their applications, equipment and techniques. HTHP covers the thermophysical properties of gases, liquids, and solids at all temperatures and under all physical conditions, with special emphasis on matter and applications under extreme conditions, e.g. high temperatures and high pressures. Additionally, HTHP publishes authoritative reviews of advances in thermophysics research, critical compilations of existing data, new technology, and industrial applications, plus book reviews.
