Thank you in advance for your help RonG and excuse me, I recognize that it is a too general question. I will try to specify the question a little more.
Mainly, I need information about furnace brazing applications of Ni alloys (Inconel and Hastelloys) in Marine Gas Turbines. I would like to know what are the most used furnace atmospheres (vacuum, hidrogen...), the most used filler metals (silver base, nickel base...) and the main precautions that you must consider on brazed joints (embrittlement by sulfur and low-melting metals, cleaning prior to brazing, stress corrosion cracking, etc.)
I suppose that the alloy physical metallurgy (solid solution or precipitation hardened alloy) will be very important when you must choose the suitable brazing procedure.
I hope that this details help you.
