Texture and Microstructure in Ni-W Alloy Tape Manufactured by the Powder Metallurgy Process

Article Preview

Ni-3at.%W alloy tapes for YBCO coated conductor were fabricated by powder metallurgy process including powder compaction, cold isostatic pressing(CIP), cold rolling and annealing for recrystallization. The Ni-3at.%W tapes annealed in an atmosphere of 96%Ar and 4%H2 mixing gas were characterized by X-ray pole figures, orientation distribution function(ODF) and optical microscopy(OM). The Ni-W alloy tapes were heat-treated at 700~1000°C for the development of cube texture {001}<100>. The texture analysis indicated that as fabricated tapes have a sharp cube texture after annealing at 900 and 1000°C. Also, thoroughly recrystallization takes place for the annealed tapes at the both temperatures and the average grain size of the two tapes is about the same, which is about 35㎛.
