Fig.2 Schematic of the measurement zone (a) and SEM images of the composite interface of composite stainless steel rebar with reduction rates of 20% (b), 40% (c), and 60% (d) at 1000 oC (Black dash lines in Figs.2b-d show the boundaries of carburized layer, and red dash lines show twin boundaries. The schematic of the measurement zone is illustrated by an example with reduction rate of 40%)
