Hello, I'm having a hard time stamping and annealing grade 2 Ti foils (0.0125mm thickness). The ductility appears to decrease significantly after I vacuum anneal the Ti foil after stamping. I'm running them at a vacuum of 10-6, 700 deg C for 2 hrs and I seem to be making them worse than if I don't anneal them at all. I'm looking for a fully annealed part after stamping. Any ideas on how I can achieve this?
