Refractory metal annealing bands

摘要

The invention relates to a process for making an annealing band, the process comprising (a) producing a refractory metal powder; or refractory metal alloy powder; (b) optionally blending the powder with an oxide component or a carbide component; (c) consolidating the powder or powder blend and forming a consolidated powder component; (d) subjecting the consolidated powder component to thermo-mechanical treatment and forming a sheet, or tube; (e) cutting the sheet into a strip; and (f) forming an annealing band from the strip. Then invention also relates to annealing bands and processes for using annealing bands.
