That's Exactly what I'm looking to do Ed. I know that the temperature needs to be below 200 degrees C(as to avoid softening the copper) but I'm looking more for advice on how long to heat the material and how long to cool, to remove as much of the residual stress as possible
The part that i'm working with has issues with its stainless base becoming warped while in service. One of the things we are looking into is the possibility that there is stress being induced by the machining done post braze and if that's the case they may be causing the issues that we are seeing.
I'm doing some research into Stress relieving of a stainless steel (304L) part that has been vacuum brazed to OFHC copper. My issue is finding the correct constraints (eg... Temp,Heat time,Cool time) in which the stainless can be stress relieved without softening the copper. If anyone has some...
