I mount a lot of samples in bakelite, but am not familiar with your use of epoxy. Are you sure the epoxy is fully cured and isn't outgassing in the process? I've found any moisture in the enclosure will give you problems.

minimotorsports: Get in touch with Paul Beaulieu or Chris Rinaldi at Excel Technologies (Enfield CT; www.extec.com ) They should be able to place you with someone. good luck.

http://www.alicona.com/ Their Infinite Focus Instrument is capable. I use one regularly.

If chemical spot tests are what you're looking for, get a copy of ASTM publication STP 550: "Nondestructive Rapid Identification of Metals and Alloys by Spot Test"

We've been very successful with eddy current testing. Check these sources "Contactless Diameter Measurement of Wires Using Eddy Current" at www.uwic.ac.uk/sped/research/AppliedSignalsProcessing/ Publications/Test%20and%20Measurement.pdf and http://www.foerstergroup.com/index.html

There's a lot to choose from. I just etched a piece with 6H2O-6HCl-2HNO3, immerse for about a minute or so. Very good results.

The tungsten wire will have a hard drawn, fibrous microstructure at first, and will be pretty flexible, otherwise it couldn't be coiled and re-coiled to make light bulb filaments. Recrystallization occurs at about 1200C, and then it will be very brittle at RT. The major benefit to using...

Just for the record, the folks in the lighting industry dissolve out the Mo mandrels that tungsten wire is wound on by soaking in a HNO3/H2SO4 solution for a few minutes @50C. Doesn't affect the Re in W-3Re coils either.

I regularly bond neoprene to wood with CA adhesive, which works exceptionally well. Perhaps it would work as well with other materials

This subject seems relevant to our problem where we are using cemented carbide wheels to score glass tubing in high speed production. Would a TiN-coated material be better, since we are losing a lot of carbide wheels due to chip-out on the cutting edges?

Pure tungsten will recrystallize to an equiaxed structure @1200C, and in this condition is extremely brittle at RT. Lamp grade tungsten is doped with potassium (~80ppm) which impedes GB growth, raising the re-x temp to @ 2000C, and imparting ductility when cool. However, Fe, Ni, and Al on the...

We're doing some experiments at 800C in hydrogen, but the SS foils we're using are rapidly failing, presumably due to hydrogen embritlement. What other metals/alloys can I try?
