Abstract
Mechanical properties of the orthorhombic phase of YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} (Y123) at room temperature have been investigated at different applied loads: 5, 10, 30 and 100 mN using a nanoindentation technique. This study was carried out for different monodomains on the (001) plane for textured Bridgman samples with dispersed particles of Y211 as pinning centres. Hardness and Young's modulus values were calculated using the Oliver-Pharr approach. Nanohardness and Young's modulus for the Y123, Y{sub 2}BaCuO{sub 5} (Y211) and Y 123/Y 211{sub composite} (YBCO) were determined using an applied load of 5 and 10 mN. For higher loads, it is not possible to differentiate the matrix (Y123) from the precipitates (Y211). In this case, only hardness and Young's modulus of the YBCO composite can be determined. Finally, the ultra-low load imprints obtained by nanoindentation have been correlated with parameters obtained by atomic force microscopy (AFM) and field emission scanning electron microscopy (FE-SEM)
