| Abstract |
Vitreous cylinders with compositions Bi2-xPbxSr2CaCu2Oy, (x = 0 and 0.4) were prepared and used
as precursors to fabricate textured bars through a Laser Floating Zone melting method (LFZ). The
resulting textured cylindrical bars were annealed and were mechanically characterized through
mechanical strength, σ, Young modulus, E, Vickers hardness, H, and Weibull parameters, S0 and m.
The study of the mechanisms controlling the fracture process was made by means of the
fractographical analysis using Laser Scanning Confocal Microscopy (LSCM). Finally, the
microstructure was determined and correlated with the mechanical properties. |
