N2 - The hydrogen absorption of the systems (Zr//xTi//1// minus //x)B//2 (B EQUVLNT Cr, Mn; 0 less than equivalent to x less than equivalent to 1) was investigated as a function of x to check a previously proposed phenomenological model for the hydrogen capacities of Laves-phase AB//2 pseudo-binary compounds. The measurements were performed at pressures between 40 and 300 atm at room temperature and at liquid nitrogen temperatures. At 40 atm and 80 K the absorption capacity of the pseudo-binary compounds (Zr//xTi//1// minus //x)Cr//2 increases linearly from 3. 3 H atoms (formula unit (f. u. ))** minus **1 in TiCr//2 to 4. 5 H atoms (f. u. )** minus **1 in ZrCr//2. The maximum absorption capacity N//H of the system (Zr//xTi//121 31 //x)Mn//2 steeply increases from N//H equals 0. 3 H atoms (f. u. )** minus **1 for x equals 0 to N//H equals 3. 65 H atoms (f. u. )** minus **1 for x equals 0. 4; it stays practically constant at approximately 4 H atoms (f. u. )** minus **1 in the range 0. 6 less than equivalent to x less than equivalent to 1.
