Micro-compression tests were carried out on pillars of 60 ?m in diameter, milled by plasma focused ion beam porous Yttria-Stabilized Zirconia (YSZ) pellets. The fracture properties determined over a wide range porosities (33 %–63 %) for 8YSZ and at given pore volume fraction 63 % 3YSZ. mechanical from testing reproducible thanks to the homogeneity microstructures. Young’s modulus was estimated ...
