Distribution of the volume fraction of (Fe,Cr)₂₃C₆ crystals of various sizes estimated by fitting in-situ small angle neutron scattering intensity measured during isothermal annealing of the sintered sample at (a) 700 °C and (b) 725 °C for 100 min. The crystals exhibit a range of radii from 3 to 18 nm.
