The rate of reaction between zirconium-- titanium alloys, containing 50 and 55 atomic per cent zirconium and hydrogen, was studied under static and flow conditions. It was shown that under most conditions studied the reaction is first order. The effect of surface state and of impurities in the hydrogen on the reaction was investigated. For comparable static and flow experiments at 550 deg C the reaction rates determined were 2 x 10/sup -6/ g/cm/sup 2/ min mmHg and 0.5 x 10/sup -6/ g/cm/sup 2/ min mm Hg, respectively. The calculated activation energies for the reaction are 4.1 kcal/mole between 400 and 520 deg C, and 15.7 kcal/mole between 520 and 600 deg C. A brief comparative study with unalloyed zirconium showed the reaction to be flrst order and gave an activation energy of 17.3 kcal/mole between 400 and 470 deg C. (auth)
