Either beryllium or the Group IV or V metal or both are in some instances substituted for in part by selected metals up to the solubility limit in the phase structures. Exemplary systems are based on Be2 Ti with substitutions made to increase the stability of the hydride, or are based on Be2 Zr with substitutions made to decrease the stability of the hydride.Other References
