| Outline of Final Research Achievements |
I succeeded in development of the production unit with which it was connected in the atmosphere and in the high vacuum furnace. Hard grains were glued temporally in the atmosphere and the continuous production off which the wire brazed during a vacuum is reeled in the atmosphere again was done. It was achieved to produce less than 50 μm of thinnest fixed grain type saw wire which is the purpose of this research and process a diamond substrate. Decomposition behavior of titanium hydride at high temperature was considered and wettability of a diamond and solder material was improved. cBN, hBN, a diamond and fullerene were employed as hard grain. I keep collaborate research with explosive manufacture synthesis of a wurtzite type boron nitride (wBN) which was explosive synthesized by hBN.

| Academic Significance and Societal Importance of the Research Achievements |
次世代のパワー半導体としてダイヤモンドが期待されているが、硬質砥粒を固定したソーワイヤにより加工が可能であることを示した本研究成果は産業的な意義がある。また、ダイヤモンド砥粒を強固に接合するために、水素化チタンの昇温速度による分解特性を明らかにしたことは学術的に意義がある。また、直径50μｍ級のソーワイヤにより、ロボットなどの微小部品をダイヤモンドで置換することにより信頼性と長寿命化が図れる。
