The results obtained are summarized as follows. (1) The surface layer was softer than the interior. The thickness of this layer was about 50 μm. (2) It is isterpreted that the formation of this soft surface layer was becaused by the depletion of Mg atoms due to oxidation of Mg atoms near surface. (3) The soft surface layer has an effect of rasing the fatigue strength to repetitive tensile loading.}, pages = {169--175}, title = {Al-3mass%Mg合金の疲労強度に及ぼす表面層の影響}, volume = {30}, year = {1995}, yomi = {カナダニ, テルト and ホソカワ, ノリオ and タニモト, タダシ} }
