Outline of Research at the Start

我々が開発した超高温高圧気泡の温度、圧力を制御し、従来にないアルミニウム合金のピーニング時効処理技術を開発する。ピーニングとは、表面に圧縮の残留応力を与える技術の総称である。時効処理とは、Al合金に余分に含まれるマグネシウムやシリコンという原子が移動して原子層サイズの析出物を形成し、合金が変形するときの障害となって硬く強くする熱処理である。本技術では、気泡が破裂する際の圧力で表面を叩き圧縮の残留応力を与えるとともに、気泡内のガスの熱が表面を加熱する処理を同時に行うことができる。本技術をAl合金からなる自動車部品や航空機部品の製造過程に組み込み、構造強度を飛躍的向上させることを目的とする。

Outline of Final Research Achievements

We have developed a novel peening aging treatment technology for aluminum alloys by controlling the temperature and pressure of the new ultra-high temperature and pressure cavitation (UTPC) that we have developed for the first time in the world. Using an aluminum alloy (AC4CH), we were able to establish peening artificial aging conditions that extend the fatigue life, improve the fatigue strength, fatigue limit compared to fatigue test specimens prepared by increasing the surface strength with conventional shot peening.
As a result of this research, it will be widely used as a production technology for shortening the aging treatment time in the parts manufacturing line of transportation machinery such as automobiles, improving the fatigue strength of existing transportation machinery aluminum parts, and realizing thinning and energy saving of parts.

Academic Significance and Societal Importance of the Research Achievements

アルミニウム合金は、輸送機械である自動車や航空機、車両等の多くの部品に用いられている。鉄やステンレス鋼に比べて比重が小さく、輸送機械の軽量化を図ることができる。Al合金は時効処理を行って機械的強度を高めている。しかしながら、従来の表面改質では、表面硬度や耐摩耗性、耐焼き付き性を高めても、構造強度を向上できないという問題があった。
本研究の超高温高圧キャビテーション処理では、ウォータージェット圧力、超音波出力及び加工時間の適正化を図ることにより、表面に圧縮残留応力を付与するのみならず、時効処理や溶体化処理を行うことができるため、Al合金からなる部品の構造強度を飛躍的向上させることができる。
