Hi, I have a drawing that calls out ASTM E1417 Type I method A, form d, class 2. Is solvent remover class only specified on ASTM E1417 Type I, Method C or could it be specified if "form d" (nonaqueous) developer is used?

In AMS 2774, does anyone know what the metallurgical reason for the higher annealing temperature at 2050 F temperature for alloy 625 if brazing will follow? Normally, annealing would be at 1900 F, but footnote 9 in rev G requires a 2050 F anneal if high-temperature brazing is to follow.

Does anyone know a good resource for searching for manufacturers of titanium metal matrix composites?

Either cold worked or annealed. I need to be able to convert between microhardness (Knoop/Vickers) and Rockwell.

Is ASTM E140 Table 3 (high nickel alloy) the appropriate table for converting microhardness to Rockwell for 304L stainless steel?

Where do I measure underfill from when I have mismatch? In this attached figure, should it be "A" or "B"? I can't find guidance in AWS D17.1.https://files.engineering.com/getfile.aspx?folder=37b4d1fb-93dc-447a-9062-0c9789ce55f6&file=welder_cert_7773.jpg

The main issue is not whether there are capable facilities but more if they are willing to do only one part.

I am having trouble finding a supplier with the capability of making large diameter (~55 ") flash welded rings in high temperature alloys such as RA 330 and Inconel 601. Does anyone have any suggestions?

Does anyone know where I can find hydrazine compatibility with silver plate and TiN coating? I couldn't find it in MAPTIS.

Hi MagBen, Our material is in the cold worked condition. It operates in the 600–1000 °F range.

I am having trouble finding creep curves for Elgiloy. Does anyone know a good resource?

the all around symbol is not the issue. Please see clarifying diagram. The issue is the arrow side and other side references. https://files.engineering.com/getfile.aspx?folder=28086e4a-953c-44ae-a65f-d877ef3b9d76&file=New_Microsoft_PowerPoint_Presentation.pptx

Would you interpret this symbol this way or is this incorrect? Should I have two symbols instead?https://files.engineering.com/getfile.aspx?folder=bde4cf37-a233-4c4c-abee-79fda1bd023e&file=New_Microsoft_PowerPoint_Presentation.pptx

We have it in the annealed and then cold worked condition. I am only able to roughly estimate the % cold work based on the microhardness.

I was able to obtain charpy data for cold worked inconel 625, but don't know of a good correlation from Charpy to Kic or Jic. Anyone have any suggestions? I know there is a correlation for steels, but I have nothing to say whether that is applicable.

We are using this alloy called VACOFLUX 9CR. Unfortunately, the manufacturer does not have fatigue characterization of it. Does anyone know of a similar alloy that may have fatigue data associated with it?

Plug made of 316 screwed into housing of 6061 aluminum but with Inconel X750 boss seal in between. Surface area ratio might be favorable.I might be able to leave this in if I have a sufficiently low galvanic current according to the NASA standard 6012 referenced.

condensate from a possible launch site where marine mist is possible.

I have a situation where there are two dissimilar metals in contact with each other. They will be exposed to cryogenic temperatures, so there is a possibility of moisture wetting. I know the approximate potential in sea water service. I was looking for a way to conservatively estimate the...

yes, I've tried. I coulnd' find a spec for cold worked 625 either. Yield and Ultimate tensile strength.
