Abstract:

A systematic investigation of temperature - pressure - time variables for dehydriding titanium alloy Ti-6246 powder was made to determine practical processing conditions for reducing the hydrogen content of the powder to levels below 100 ppm. Analyses of the experimental results of tests made between 1200F and 1500F indicate that 1500F is the optimum dehydriding temperature. The controlling process for dehydriding can be expressed by second order reaction 2Hgas H2 gas with an activation energy of 21,760 plus or minus 1840 cal. Below 0.088 micron partial pressure of hydrogen, the type of vacuum system used for dehydriding is believed to be the major factor for removal of these molecules.
