Heat treatments have been performed in a laboratory furnace NABERTHERM model N31/H (using Argon as inert gas), range 100÷1280°C, with wall thermocouples calibrated as per internal procedure PT-7/10 Rev.10. Piece temperature being checked through contact thermocouples connected to an external digital tracker; tracker and thermocouples previously calibrated according to the same internal procedure.
