Conclusions
-
1.
Different titanium alloys ignite when ruptured in media containing oxygen under a pressure above a certain critical value. This critical oxygen pressure differs for each alloy.
-
2.
Apparently it is impossible to create sheet titanium alloys with high plasticity which are resistant to oxygen under pressure. A titanium alloy with the intermetallic compound TiAl as a base which contains 30% Al does not ignite in oxygen under a pressure of 100 atm.
-
3.
An increase of the temperature from 20 to 1000°C decreases the critical pressure of oxygen required for ignition. A decrease of the concentration of oxygen in the medium increases the critical pressure of oxygen.
