Fig.8 Bright-field TEM images of reverted austenite in the Cu-contained maraging stainless steel samples aged at 480oC for 0.5 h (a), 24 h (b), 60 h (c), and 90 h (d) (Inset in Fig.8b shows the corresponding SAED pattern, indicating the Nishiyama-Wasserman relationship of reverted austenite and matensite. M represents martensite)
