    Rene' 95

    Thank you, all. I am trying to determine if the component saw an excessive temperature condition. I still see coarse and fine gamma prime; therfore I agree with EdStainless that the Rene'95 is still in the correct heat treat condition.

    Thanks EdStainless. Yes I have. This is a rotating air seal and I am doing in-situ. I have also tried numerous electrolitic etchants. The grain size should be 10 or finer. I have beautiful pricipitates and a very even microstructure, but need to measure grain size.

    I need an etch to show grain size on Rene' 95. Any history with this alloy? I have tried numerous etchants with very little sucess.
