Research and Development Super Heat Resistance Structural Materials |
|---|
| Intermetallic-compounds for high-temperature structural materials, which are expected to be applied in the field of aero-space, have been researched by co-operative R&D by private and public sectors. In our institute, basic research of powder metallurgies of titanium-aluminide (Ti-Al) with high specific strength and niobium-aluminide (Nb-Al) with a high melting point has been carried out to realize both the near-net shape process and excellent mechanical properties. |

Semi-solid Forming Process of Magnesium Alloys |
|---|
| Magnesium alloys are the most lightweight materials of all practical metals and alloys. They are easily and vigorously oxidized by air in the liquid state and consequently combust. It is very dangerous to handle them for this reason. We are trying to research and develop a semi-solid forming process of magnesium alloys in the partially melted state. Specifically we are studying structure control, and physical and mechanical properties control in the semi-solid state of the alloys. By the development of this process, formation of magnesium alloys will be attained with high accuracy and safety. Lightening of transportation materials, industrial equipment materials, and electrical machinery and appliances materials can be hereby promoted. |

Surface Modification of Materials by Ion implantation |
|---|
| Ion implantation is an attractive processing technique, which can modify the composition and structure of material surfaces with excellent controllability and reproducibility. Since this technique is applicable to alteration of various materials, such as metals, semiconductors, ceramics and polymers, and is able to give them many advanced functions, it has attracted much attention from the fields of electric and optical devices, various sensors, energy related materials and biomaterials. Foundational research of the surface modification mechanism by ion implantation is one of the most important subjects at NIRIN, as well as the development of ion beam technology. | ||
