Thanks for the quick response... I suspected the same. My only concern is that perhaps the temp might be just high enough to cause some carbide precipitation. It appears this will not be a concern.
Thanks again
I am looking for help with a new product our company is working on. Does anyone know the effects of "stress relieving" 302 HQ to the following parameters. The reason I question this is because the typical stress releive would be at 1650F. I was wondering what the effects of the modified...
Does anyone have any recommendations for etching 6-6-2 titanium in the STA condition? Some prefer Kroll's while some prefer a combination of Oxalic and Kroll's. Boeing recommends Kroll's but I am not getting good results. If I swab the specimen after etching, the structure is much more...
Dose anyobe have advice on how to produce IGA / IGO on 8740 and A286 samples. This is for round-robin testing to fulfill NADCAP requirements. Basically, I am trying to determine how to cause the condition to produce test samples.
Thank you everyone for your time and expertise. We have also come to the conclusion that the parts are tp be scrapped. Our only option is to go to the customer for a waiver and the thought is why should they accept the responsibilty? It's a tough call to make but ultimately it is the right...
The material is to AMS5662 and it is in coil form. It is bought in the solution annealed condition with subsequent cold reduction of 15/17 percent. This is done to boost the shear strength and is required by our customer this way. Unfortunately, this particular part prohibits us from re-solution...
Thanks, I have this bulletin as well. The only problem is that my procurement spec does not allow me to solution anneal again because I will lose my necessary cold working in critical areas of the part.
Actually, before the furnace reached temperature for the higher temp. Testing is fine but NADCAP auditors believe in the charts and spend considerable time looking them over. Most findings stem from the charts.
I would like to know the concern of double aging Inco 718. Basically, our aging cycle is 1325 8hrs, cool in furnace at 100 degrees per hour until 1150, then hold 8 hours with an air cool. Basically, our furnace chart got stuck and I have no objective evidence that the cycle was fulfilled...
