Impact Sensitivity of Metals (Titanium) Exposed to Liquid Nitrogen Tetroxide

Abstract

The purpose of this investigation was to determine the impact sensitivity of commercially pure Ti, Ti alloy 6Al-4V, and precipitation hardened 15-7 Mo stainless steel when exposed to liquid N2O4. An explanation is given of the probable mechanism of the limited ignition resulting from impact. Commercially pure Ti and Ti alloy 6Al-4V ignite about 50 percent of the time when impacted with a 0.5-in.-diam flat striker having an energy of 200 ft-lbs. Storage of the commercially pure Ti in N2O4 decreases the energy needed for 50 percent ignition to 60 to 70 ft-lbs. The sensitivity of the alloy is unaffected by storage in N2O4. Precipitation hardened 15-7 Mo stainless steel was not impact sensitive in liquid N2O4.
