HYDROGENATION CHARACTERISTICS OF TIFE1-XPDX ESS-THAN-OR-EQUAL-TO-X-LESS-THAN-OR-EQUAL-TO-0.30) ALLOYS

Pseudobinary TiFe1-xPdx (0.05 less than or equal to x less than or equ al to 0.30) alloys have been investigated on their crystal structure a nd hydriding behavior. The lattice constant increased with an increase in the substituted amount of Pd with maintaining the CsCl type crysta l structure, The partial substitution by Pd with superior catalytic an d hydriding natures were effective for mitigation of their activation conditions to a considerable extent. The substitution resulted in lowe ring the plateau pressures ascribed to formation of the monohydride in the PCT diagrams.
