Ni-Cr textured substrates with reduced ferromagnetism for coated conductor applications

A series of biaxially text U red Ni1-xCrx materials, with compositions x = 0, 7, 9, 11, and 13 at. %Cr, have been studied for use as substrate materials in coated conductor applications with high temperature superconductors. The magnetic properties were investigated, including the hysteretic loss in a Ni-7at.%Cr sample that Alas controllably deformed; for comparison. the loss was also measured in a similarly deformed pure Ni substrate. Complementary X-ray diffraction studies show that thermomechanical processing produces nearly complete {100}<100> cube texturing, as desired for applications. (C) 2001 Elsevier Science B.V.
