Sažetak
A structural and thermodynamic study of the DyNi5-xAlx - hydrogen system has been performed. It was found that the hexagonal crystal structure of the prototype compound DyNi5, exists up to DyNi3Al2. Beyond this composition and up to DyNi2Al3 another related hexagonal structure is stable. All alloys have been exposed to hydrogen gas at pressures up to 15 MPa and temperatures between 77 and 700 K. Under these conditions ternary alloys up to composition DyNi3Al2 react reversibly with hydrogen. The pressure-composition isotherms were measured. The entropy and the heat of formation have been extracted for systems that exhibit pressure plateau. It was found that the hydrogen capacity and the equilibrium pressure decrease with the increasing content of aluminium.
