The grayscale images were segmented into black/white, resolution: 1 µm/px. The samples were either sintered from spherical or formless particles. The nomenclature of the samples is according to: a) Ti45: spherical, HDH: formless particles, b) Thickness of the samples / µm, c) Sinter temperature / °C, d) IEKxx: sample lot, e) Size of the segmented image section, the third dimension is the through-plane direction. A detailed description was published by Borah [1].
