The Computational Mechanics Conference   2013(26) "1417-1"-"1417-2"   Nov 2013
濃度変調と積層変調が同期した新奇な構造(シンクロ型LPSO構造)を持つLPSO単相合金及びAI合金を凌駕する機械的性質を有するMg相とLPSO相からなるMg基シンクロ型LPSO合金に関して,その場パルス中性子回折により応力応答の評価を行った. 18R LPSO単相合金の引張応力に対する格子ひずみの応答は,a軸とc軸との間に異方性が見られた.また2相合金では,LPSO相が強化を担っており,低18R LPSO 体積分率押出合金では,降伏応力まで,測定した範囲で,Mg相と18R LPSO 相応力...
