a Phase identification via X-ray diffraction (XRD) analysis for SA, 1H, and 24H alloys. b–d Scanning electron microscopy (SEM) images and electron-backscatter diffraction (EBSD) phase maps for different ageing times, (e–i) transmission electron microscopy (TEM) images and atom probe tomography (APT) reconstruction and proximity histogram across precipitates and bcc matrix for 1H alloy. The 50 at% Co iso-concentration surface shows the reference phase boundary. j,k,m,n TEM images, (l,o) corresponding fast Fourier-transform (FFT) images, (p,q) APT reconstruction and proximity histogram for 24H alloy.
