本研究は,原子配列がどの方位にも無理数比なインコメンシュレート条件である準結晶の原子論的な量子摩擦・摩耗に対する実験的基礎データの収集および超潤滑理論の検証のための基礎実験を」行うとともに新しいトライボ材料としての準結晶の可能性の探索を目的とした.これらの目標を遂行するため,第一に粒界などの欠陥のないAl-Cu-Fe系単準結晶の創成をおこなった.次に摩擦係数測定,摩擦摩耗現象に相関のある弾性定数,破壊強度,硬さの測定をナノインデンテーション法で行い,ほぼ同組成の結晶相の材料と比較を行い,準結晶材料の特徴を明らかにした.以下に,得られた結果について示す.(1)TFZ法によりAl_<61.6>Cu_<24.5>Fe_<13.9>の組成のmmサイズの単準結晶を創成できた.X線回折法および透過電子顕微鏡観察により5回の回転対称性を有する単準結晶であることを同定した.(2)得られた単準結晶の物性は,摩擦係数(大気中)0.18,縦弾性定数191GPa,ビッカース硬さ970,破壊硬さ1.7MPam^<1/2>であった.一方同組成の結晶相はそれぞれ0.25,136GPa,690,1.1MPam^<1/2>であった.従って,準結晶相は特異な原子配列に起因して摩擦係数,強度などで優れており,低摩擦,高比強度材料として有望であることがわかった.

In this study, the atomic configuration of the azimuth is irrational than the condition of the quantum friction of the atomic theory. in this study, the atomic configuration, the azimuth, the irrational number, the condition, the atomic theory, the quantum friction, the friction, the atomic theory, the atom, the azimuth, the irrational number, the condition, the condition, the In the first place, the grain boundary is lower than that of the Al-Cu-Fe system, and the results show that the grain boundary is low. The friction coefficient is determined, the friction consumption is determined, the strength of the friction is determined, the strength of the friction is determined, the friction coefficient is measured, the friction coefficient is determined, the strength of the friction is determined, the friction coefficient is determined, the friction coefficient is determined, the friction consumption is determined, the strength of the friction is determined, and the properties of the materials are compared. The following tests are available. (1) TFZ method is used to evaluate Al _ & lt;61.6>Cu_<24.5>Fe_<13.9&gt. The composition of the mm temperature test results showed that the results were in good agreement with each other. X-ray fracture back analysis method was used to observe the thermal stability of 5 cycles through the computer micrograph. (2) the mechanical properties of the test results are the same as those obtained. (2) the physical property, friction number (medium), fatigue number (191GPa), fatigue hardness 970, hardness 1.7 MPam^ & lt;1/2&gt are obtained. There's nothing wrong with it. One side has the same composition as the crystal phase. The crystal structure is 0.25136GPA. 690,1.1 MPam ^ & lt;1/2>. It is expected that the materials with high specific strength and low friction are expected to have high specific strength.
