Description

Mechanical properties of low porosity Dy123 (DyBa2Cu3Ox) bulks with different Dy211 (Dy2BaCuO5) content were evaluated through bending tests and Vickers indentation tests of specimens cut from the bulks. The bending strength and the Young's modulus of the low porosity bulks were higher than those of porous Dy123 bulks evaluated in the previous study. The bending strength of the low porosity bulks, which was decreased by the oxygen annealing, increased with increase of the Dy211 content. The fracture toughness of the area with uniform dispersion of the Dy211 particles was superior to that with low density of the Dy211 particles.
