added LHe temperature tensile and immersion testing due to
increasing customer demand! MTL has always done LN temperature
testing however companies are pushing materials to perform
in even more extreme environments. As a result, we’ve
engineered the capability to perform tensile testing under
Liquid He. Our 5 liter dewar has a double vacuum insulation
(<1 mTorr) with an LN jacket in between vacuum layers.
The wide 3” mouth allows us to lower LN pre-cooled samples,
or our proprietary tensile testing extension, into the LHe.
also begun the permitting process to allow LOX immersion testing
in early 2004. These test capabilities are virtually unavailable
from other independent testing laboratories. We are hopeful
these new capabilities will allow us to become one of the
premier testing laboratories for aerospace materials applications
