概要
- 論文の詳細を見る
Transmission electron microscopy has been used to study the structure changes in polycrystalline aluminium fatigued at very high repetition frequency (17.7 kc/sec). A number of small dislocation loops and voids were observed frequently and sometimes large loops on {012} planes. These are thought to be formed as the result of the condensation of vacancies. Rough estimation is made of the number of vacancies generated in the fatigue-process. The effect of vacancies on the fatigue life is briefly discussed.
