Microstructural evolution under tension.
EBSD images of warm rolled samples with tensile strain of (a) 15%, (b) 30%, (c) 50% and (d) 67%. All TMT samples have the same rolling reduction in thickness of 20%. EBSD images of solid solution treated samples with tensile strain of (e) 15%, (f) 30% and (g) 60%. (h) The XRD-measured volume fraction α-martensite as a function of tensile strain for both TMT and solid solution treated samples. The rolling reduction in thickness of TMT samples is 20%. The tensile tests were performed at strain rates 1.0×10−3 s−1 and room temperature. Supplementary Fig. S6 shows the corresponding stress-strain curves.
