Effect of Annealing Atmosphere on the Recrystallized Texture and Abnormal Grain Growth of Ni-5%W Alloy Sheets

The effect of the annealing atmosphere on the recrystallization of Ni–5%W alloy used as substrate sheet for superconductor wire was investigated. The annealing was made in two different annealing atmospheres: hydrogen and argon. After analyzing the recrystallized texture and microstructure by EBSD, the main texture component formed in both annealing atmospheres is the {100}<001> cube orientation. Furthermore, it is shown that hydrogen promotes...
