ABSTRACT
This work reports the mechanical properties of ab and a(b)c-plane of melt textured Y1-xPrxBa2Cu3O7-δ (x = 0.00 and 0.05) superconductor. Y1-xPrxBa2Cu3O7-δ have been prepared by top seeding technique. Hardness and elastic modulus were obtained by instrumented indentation. Independent of the plane, the hardness values were around 5.0-7.5 GPa. Young’s modulus was approximately the same for both samples for ab-plane, around 132 GPa at the deepest tip penetration. However, for a(b)c-plane, the value of Young’s modulus for x = 0.05 is higher than observed for x = 0.00 sample.
