报告题目:Nanostructured steels and high-entropy alloys for extreme environments

报告人:温海明

报告内容:There are critical societal needs to have clean energy, improve energy efficiency, and enhance the safety and reliability of energy systems. Nuclear energy is an important form of clean energy and plays a notable role in decarbonizing the economy and combating the climate change. Materials used in nuclear reactors are subjected to severe damages by the extremely harsh environments, including intense irradiation, high temperature, high mechanical stress, and corrosive atmosphere. Life extension of current nuclear reactors and development of next-generation nuclear reactors require more robust materials with enhanced properties and performance. There are two approaches to enhancing irradiation resistance: 1) engineering microstructure of existing materials, and 2) developing new materials with new compositions. In this seminar, research projects will be discussed involving nano science and engineering in an effort to manufacture and evaluate nanostructured steels with enhanced mechanical properties and irradiation resistance (steels are the most used materials in nuclear reactors). New materials, specifically high-entropy alloys, have also been developed, fabricated using different manufacturing techniques, and assessed for mechanical properties, high temperature stability and irradiation performance. The microstructures of the materials are tailored on the nanometer scale in order to achieve enhanced properties.
