In this issue, the effect of gas heat treatment ambient at the temperature of 950C
for 8hours using the gases NH3 or CH4 and using the gases NH3 and CH4 for
(4+4)hours of the distribution of the doping elements on Titanium alloys BT9 was
studied.
Oxide formation at the different treatment ambient as a reason of gas-phase
oxygen distribution to high depths in the samples was discovered.
