【摘要】 核能系统苛刻的服役环境对核用材料提出了极高的要求。钼及钼合金因其优异的高温力学性能、较低的热膨胀系数、良好的导热性与液态金属相容性以及相对低的中子捕获界面,使其成为满足新一代核能技术发展的重要候选材料。本文综述了几种典型的钼和钼合金的力学性能及其在核反应堆环境下的应用、抗腐蚀性能和抗辐照性能研究现状,展望了本领域需要进一步关注的热点问题,期望为满足核领域不同用途钼及钼合金的成分、组织、性能设计研究提供思路。更多还原

【Abstract】 The harsh service environment of nuclear energy systems places extremely high demands on nuclear materials. Molybdenum and molybdenum alloys,due to their excellent high-temperature mechanical properties,low thermal expansion coefficient,good thermal conductivity and liquid metal compatibility,and relatively low neutron capture interface,make them an important candidate material for the development of a new generation of nuclear energy technology. This article reviews the mechanical properties of several major molybdenum and molybdenum alloys and their applications in nuclear reactor environments,corrosion resistance and radiation resistance research status,and looks forward to the hot issues that need further attention in this field. The field uses molybdenum and molybdenum alloy composition,structure and performance design research to provide ideas.更多还原
