The research project of 'Research and development of highly equipped experimental technique for materials in light water reactors' started in 1995 and have continued to 1997 for three years. This report is the summary of the research project which includes the following for results.(1) Microstructural evolution under electron and ion irradiation in zirconium alloys and their oxide films : we have determined the migration energies of interstitials and vacancies to be 0.1-0.22 and 1.0-1.1eV,respectively.(2) oxidation mechanism of zirconium alloys by using 'in situ' measurements of electrical conductivity under 1 MeV electron irradiation : the rate controlling process of electrical conductivity in zirconium oxide was electron migration. This indicate that the rate controlling process of oxidation is the migration of oxygen ions.(3) development of ultra-microhardness and Vickers hardness technique for evaluating stress-strain properties of metals : From the measurements of the load-dependence of hardness and plastically deformed area, we have proposed a new method for evaluation stress-strain properties, that is, the yield stress and strain hardening exponent of metals by using ultra-microhardness and Vickers hardness technique.(4) Radiation hardening of ion-irradiated metals and oxide ceramics by using the ultra-microhardness technique : high energy ion irradiated copper was subjected to evaluate stress-strain properties by using the proposed ultra-microhardness technique.

“轻水堆材料高装备实验技术研究与开发”研究项目从1995年开始，到1997年持续了三年。本报告是该研究项目的总结，包括以下成果：(1)锆合金及其氧化膜在电子和离子辐照下的微观结构演化：我们确定了填隙和空位的迁移能为0.1-0.22，分别为1.0-1.1eV。(2)通过使用1下电导率的“原位”测量来研究锆合金的氧化机理MeV电子辐照：氧化锆中电导率的速率控制过程是电子迁移。这表明氧化速率控制过程是氧离子的迁移。(3)用于评估金属应力应变特性的超显微硬度和维氏硬度技术的发展：从硬度和塑性变形的载荷依赖性测量在此领域，我们提出了一种评价应力应变性能的新方法，即利用超显微硬度和维氏硬度技术来评价金属的屈服应力和应变硬化指数。(4)金属的辐射硬化使用超显微硬度技术进行离子辐照的金属和氧化物陶瓷：使用所提出的超显微硬度技术对高能离子辐照的铜进行应力应变性能评估。
