The parent grain reconstruction of the two-stage martensite transformation γ to ɛ to α′. (a) The phase map, showing the initial phase distribution. (b) The ORTools function peakFitORs is used to fit both ORs on the basis of the parent–child misorientation angle distribution. (c)–(e) The inverse pole figure maps of (c) γ, (d) ɛ and (e) α′ show the initial grain orientations. (f), (g) The sequential reconstruction of (f) α′ to ɛ and (g) reconstructed + retained ɛ to γ is carried out in a single workflow. All scale bars are 5 µm. The colours in (c) and (e) are as per the inset stereogram in (g), whereas the colours in (d) are as per the stereogram in (f).
