New Protium Function in Sub-Nano Materials

在21 st century that Environmental Management 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 res？results of this priority area turned out to be Magnificent。本项目的主要结果之一将通过使用处理功能的原理来改进功能材料的特性。基于钛的合金合金，适用于低微米的碱性吸收率，最多可达9300%，超塑性与细粒度以下的超塑性延伸。这个项目中的第二个目标是在100以下的3质量%以下的地方。必须开发，几乎可以使用Ti-Cr-V合金，V含量低，不含V的Ti-Cr-Mo合金也能获得相同的特性。机械上的地面碳或镁碳复合物还显示了7.3质量%的吸收特性。在高密度的Protium合金和受保护的受保护的地方的新结果中，Protium也被发现。作为proium-inducuced的新功能材料，Zr-Cuamorphous合金显示高阻尼性能，通过添加硅到合金。各种多孔材料也是通过使用固体和固体金属之间的溶解性差异来开发的。可以肯定的是，目前项目的目标是完全可以完成的。在事实上，审查研究结果的委员会已经得到了[A] （研究已被预期完成），将其作为新功能的优先领域。

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.
