Melt texturing of NdBa
We have melt processed
NdBa2Cu3O7-8-Nd4Ba2Cu2O10 (NdBCO)
superconducting composites with various rates of cooling through
their peritectic formation temperature. The microstructural studies
reveal that the sample processed even with 40°C/h rate of
cooling is built up with aligned microstructure which is necessary
for superior transport current and magnetic properties. In the
case of YBa2Cu3O7-8, 1°C/h rate of cooling is
necessary to get highly textured microstructure. Magnetic flux
profile measurements reveal that even though the intradomain region is
well textured and had good transport and magnetic properties, the
interdomain region is relatively weak in the fast cooled sample in
comparison with slow cooled ones but is much better than that in
polycrystalline samples. The results suggest that, the NdBCO
superconductor can be melt processed in short time with much
better microstructural features in comparison with YBCO system
