Magnetization loops were measured on struts of superconducting YBa 2 Cu 3 O$_{x}$ (YBCO, 123-phase) foams taken from various positions of a 5 × 2 × 2 cm 3 large foam sample prepared at RWTH Aachen. From these data, flux pinning forces, $F_{p} = j_{c} \times B$, were calculated and pinning force scaling diagrams $F_{p}/F_{p,\max}$ versus h = $H_{a}/H_{\rm irr}$ were established. The scaling in the temperature range 60 K ≤ T ≤ 85 K was found to be well developed for all samples with peak positions, h 0 , above 0.4, which is an indication of δ$T_{c}$ pinning. From microstructure analysis using the electron backscatter diffraction technique (EBSD), it is known that the struts are fully converted into the 123-phase with embedded 211 particles being relatively small. The variation of $F_{p}$ depending on the position of the struts in the original sample directly reveals the changes of the texture as found employing EBSD.
