Fig. 3: Martensitic transformation in GNS 304NG under irradiation at room temperature.
From: Improved radiation resistance in metals via adaptive martensitic transformation
a Variations of α′ fraction (determined by XRD) as a function of radiation dose in GNS and CG samples. The α′ fraction values should reflect the mean volume fractions of martensite in the surface layer of ~5 μm in thickness. b A high-resolution STEM image of GNS sample at a dose of ~2 dpa. The inset shows the fast Fourier transform (FFT) pattern of the white boxed area with complete γ phase. c A magnified view of the orange boxed area in (b), showing the transformation in the lattice arrangement from γ to α′ phase. The inset shows the FFT pattern of γ and α′ mixture, indicating the formation of α′ near SFs. Source data are provided as a Source Data file.
