Abstract
The non-magnetic highly resistant to oxygenation Ni88Cr8W4 tape demonstrated to be a good metallic substrate for the production high Tc coated conductors. In this work rhe rolling assisted biaxially textured substrates (RABiTS) method has been used to promote a sharp (100)[001] texture on NiCrW metallic tape. The influence of the critical processing parameters on the cube texture development of the tape is investigated Moreover thermal oxidation of the textured NiCrW substrate has been performed at several conditions to study the oxide growth on the surface. Electron BackScatter Diffraction (EBSD) analysis was used for high resolution crystal orientation mapping of the surfaces. The microstructure of the substrates has also been investigated by X-ray and SEM. Differential thermal analysis (TG/DTA) was used to study the oxidation behavior of the NiCrW tapesI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
