中文简介:
在本课程中,我们将为理解材料在核系统中的行为奠定基础。特别是,我们将建立在核材料基础知识的坚实基础上,以便了解燃料和结构材料的辐射损害和影响。本课程包括一系列定向阅读、视频讲座、问题集、简短的研究项目以及带有工作示例的课堂讨论。我们将首先概述核材料,它们在核系统中的位置以及它们是如何失效的。然后,我们将发展晶体学的形式主义,作为世界各地材料科学家的共同语言。随后将开发热力学相图,预测二元合金系统如何走向平衡。然后介绍应力、缺陷和动力学的影响。在发展关于辐射,特别是中子和重带电粒子如何与固体物质相互作用以产生缺陷并演变微观结构的理论时,这些都将联系在一起。然后,辐射效应的一些应用将用这个新发现的框架来处理,包括辐照下材料性能的变化、空隙膨胀、脆化、延展性丧失,以及用重离子模拟反应器内辐照(中子)。
课程简介: In this course, we will lay the foundation for understanding how materials behave in nuclear systems. In particular, we will build on a solid base of nuclear material fundamentals in order to understand radiation damage and effects in fuels and structural materials. This course consists of a series of directed readings, lectures on video, problem sets, short research projects, and class discussions with worked examples. We will start with an overview of nuclear materials, where they are found in nuclear systems, and how they fail. We will then develop the formalism in crystallography as a common language for materials scientists everywhere. This will be followed by the development of phase diagrams from thermodynamics, which predict how binary alloy systems evolve towards equilibrium. Then effects of stress, defects, and kinetics will be introduced. These will all be tied together when developing theories about how radiation, particularly neutrons and heavy charged particles, interact with solid matter to produce defects and evolve microstructure. A few applications of radiation effects will then be treated with this newfound framework, including the change of material properties under irradiation, void swelling, embrittlement, loss of ductility, and the simulation of in-reactor irradiation (neutrons) with heavy ions.
