Annealing of grade 2 Ti foils

  1. Apr 13, 2017 #1
    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?

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.

    It sounds like you are annealing, but not stress relieving. Any heating up can add stress to the material. 700C @ 2 hr, is correct for annealing, then cool, then heat to 550-575C (1000-1100F) for 15-30min, then re-cool. This will help relieve stress, you have to do similar processes in steel. Feel free to double check my math, our ovens are in F.

    Are you allowing it to cool down slowly?
