Review of Investigations on Anisotropic Creep Behavior of Zr Alloy Cladding
-
摘要: 简要介绍国外在锆合金包壳管蠕变各向异性的试验和模拟研究两方面的相关研究进展。重点介绍国外在锆合金包壳管蠕变各向异性模拟研究方面的思路和方法。归纳了基于下限法、上限法及自洽法三种多晶模型开展的蠕变各向异性行为研究成果,并针对未来开展这一相关领域研究提出了建议。Abstract: The present situation of the related experimental and numerical simulation investigations on creep anisotropy of Zr alloy cladding is reviewed.In this paper the numerical simulation methods on creep anisotropy are introduced emphatically.Moreover,results on the investigation of anisotropic creep behavior,which based on lower and upper boundary and self-consistent three polycrystalline model,are summarized.Some suggestions on future research in this related fields in China are proposed.
