Abstract

Three forms of Nb artificial pinning pins, that is, island-shaped, net-shaped and layer-shaped artificial pinning centre (APC), were introduced into Nb50Ti/Cu multifilamentary composites through four-time extrusion and drawing process. Island-shaped Nb50Ti/Cu composite shows higher performance than the other two kinds of composites at high magnetic fields, and it will achieve the optimum value when the nominal APC diameter is about 30 nm. On the other hand, layer-shaped Nb APC NbTi/Cu composite shows very high critical current density and very large flux pinning force at low magnetic fields. Furthermore, upper critical fields of APC NbTi composite decreases as APC thickness is reduced.
