摘要：

We have fabricated rod based artifical pinning center (APC) composites from rods of Nb-Ti and Nb as matrix and pinning center respectively. Critical current densities of 19000 A/mm(2) at 1 T, 12500 A/mm(2) at 2 T and 3000 A/mm(2) at 5 T were achieved in a conductor containing Nb 47 wt.% Ti with 24 vol% Nb pins. Microscopy revealed a progressive degradation of the original hexagonal pinning centers from an ordered array towards more random ribbon-type microstructure as the composites were drawn towards their peak J. We review the impact of this deformation on the physical properties.
