抄録/ポイント： 時効硬化Al合金では勾配ナノ構造層の導入による強度改善無しで達成される高い延性と余分なひずみ硬化。勾配層とマトリックス間の歪勾配と異なる残留応力は主に強化された延性の原因であるが,少数欠陥(粒界析出)の出現は強度変化を説明した。圧縮残留応力は亀裂の核形成と伝搬を抑制し,協調的傾斜層における部分転位機構を活性化する。マトリックスから引張残留応力と組み合わせて,歪勾配は引張試験中に増加している。に加えて,勾配層を持つ試料が引張特性に顕著な厚さ効果を示し,欠陥で発生する圧縮残留応力を変化させることによるものであった。強化機構と欠陥からの異なる寄与を傾斜層と純金属と合金の間の有意差を行った。本研究では,傾斜材料の新しい理解,実際の複雑な材料の実用化が必須である。Copyright 2017 Elsevier B.V., Amsterdam.
