摘要
2011年发生福岛严重核事故后,锆合金包壳材料的安全可靠性受到严重的质疑,国内外对事故容错燃料(ATF)开始了广泛的研究。Mo合金由于其优异的高温性能成为了ATF的候选包壳材料之一。本文综述了Mo合金包壳材料在高温氧化性能,力学性能,抗辐照性能,中子经济性能以及加工和焊接性能方面的研究进展,并指出在工业应用中面临的挑战,最后展望了Mo合金在ATF包壳材料中的应用前景。
After the severe nuclear accident in Fukushima in 2011,the safety and reliability of zirconium alloy cladding materials have been seriously questioned,and extensive research on accident tolerant fuel(ATF)has begun at home and abroad.Mo alloy has become one of the candidate cladding materials for ATF due to its excellent high temperature performance.This article reviews the research progress of Mo alloy cladding materials in high-temperature oxidation properties,high-temperature mechanical properties,radiation resistance,neutron economics,and processing and welding properties.It also points out the challenges faced in industrial applications,and finally looks forward to the application prospect of Mo alloys in ATF cladding materials.
