Abstract
Mechanical properties of Ag added DyBa2Cu3Ox (Dy123) low porosity bulks were evaluated by bending tests of specimens cut from the bulks. The bending strength of the Ag added low porosity bulks was higher than that of a Dy123 low porosity bulk without Ag addition tested in the previous study. No significant difference in the area fraction of Ag particles was observed among the bending test specimens. On the other hand, an increase of the bending strength with decrease of the average Ag particle size was observed. It is deduced that small Ag particles effectively suppress the crack propagation.
