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21世纪，环境科学变得重要，优先领域的“新蛋白质功能”旨在系统地了解有用的蛋白质功能，并在可以包含蛋白质的各种功能材料中大大提高其特性。在四年中，该优先领域的活动和研究结果证明是宏伟的。该项目的主要结果之一是使用Protium的处理功能来改善功能材料的性质。基于Ti的合金接受了蛋白质吸收 - 吸收吸收，而高晶状体尺寸低于亚微米，可产生几乎9300％的超塑性伸长。该项目的第二个目标是，protium protium吸收的材料（3mass％以下）必须开发，几乎必须由V含量较低的TI-CR-V合金获得。机械地面碳或MG碳组成还显示了7.3mass％的吸收特性。在蛋白质合金高密度的protium占用位点的新结果中，还获得了protium诱导的缺陷。作为Proim诱导的新功能材料，ZR-CU无定形合金通过在合金中添加Si来显示高阻尼特性。还通过使用固体和熔融金属之间的Proium的溶解度差异来开发各种多孔材料。据认为，本项目的目标被认为是完全实现的。实际上，审查研究结果的委员会给出了[A]（研究简单地完成）新功能的优先领域。
