Abstract:

This revision to ERR-FW-049 AD-273 624 was prompted by the need to keep the design information on the refractory metals as current as possible. Only a few alloys were added to those covered by the original report, but the elevated temperature data presented in the curves was completely revised to reflect the properties on production material obtained during 1961. In addition, two refractory alloys were purchased in sheet form and the tests on one of these alloys were completed in time to include in this report. This alloy is the 90 Tantalum- 10 Tungsten. The other alloy is the 10 Titanium10 Molybdenum-80 Columbium alloy and will be tested during 1962. It is to be noted that vendor data on the 90 Tantalum-10 Tungsten alloy in the 2000 to 2200 F region is considerably higher than the data obtained on this alloy at General DynamicsFort Worth GDFW, indicating the wide scatter in properties obtainable on the same alloy chemistry.
