项目摘要

In the 21st century that Environmental Science becomes important, the priority area "New Protium Function" aims to systematically understand the useful protium functions and to drastically increase their properties in the various functional materials in which protium can be contained.During four years, the activities and research results of this priority area turned out to be magnificent. The one of the main results of this project is improving the properties of functional materials by using processing function of protium. Ti based alloys underwent protium absorption-desorption yield almost 9300% elongation of super-plasticity with the fine grain sizes below sub-micron. The second objective of this project where the protium absorbing materials with 3mass% below 100。・must be developed, has almost attained by Ti-Cr-V alloys with low content of V. The V-free Ti-Cr-Mo alloys also yield the same properties. Mechanically ground carbon or Mg-carbon composites also show the absorption properties of 7.3mass%.The new results in the fields of protium occupancy sites in the high density of protium alloys and the defects induced by protium are also obtained. As the proium-induced new functional materials, the Zr-Cu amorphous alloys show the high damping properties by addition of Si to the alloys. The various porous materials are also developed by using the solubility difference of proium between solid and molten metals. Accordingly, the objectives of the present project are judged to be fully accomplished. In fact, the committee for reviewing the research results gave [A] (research are accomplished expectively) to this priority area of protium new function.

在环境科学日益重要的21世纪，本研究所的优先领域“新的氚功能”以系统地了解氚的有用功能，并大幅度地提高其在各种含氚功能材料中的性能为目标，经过4年的努力，取得了丰硕的研究成果。本课题的主要研究成果之一是利用氚的加工功能来改善功能材料的性能。钛基合金经吸放氢处理后，超塑性延伸率可达9300%，晶粒细化到亚微米以下。该项目的第二个目标是3mass%低于100的氚吸收材料。低V含量的Ti-Cr-V合金几乎达到了这一要求。无V的Ti-Cr-Mo合金也具有相同的性能。机械研磨的碳或镁碳复合材料也表现出7.3mass%的吸收性能，在高密度钚合金中的钚占位位和钚诱导的缺陷领域也获得了新的结果。Zr-Cu非晶合金作为一种新型功能材料，通过在合金中添加Si，使其具有高阻尼性能。利用金属在固态和熔融态之间的溶解度差异，开发了各种多孔材料。因此，本项目的目标被认为已充分实现。事实上，审查研究结果的委员会对这个优先领域的新功能给予了[A]（研究预期完成）。
