Sažetak
X-ray powder diffraction studies of the Zr(Cr1-xCux)2 system revealed the existence of a single phase region up to composition Zr(Cr0.5Cu0.5)2. All ternary alloys crystallize with a Friauf-Laves structure of the MgCu2 type, differing from the binary compound ZrCr2 which exhibits polymorphism and crystallizes with the hexagonal structure of the MgZn2 type and the cubic structure of the MgCu2 type. It was also found that single phase alloys react reversibly to form hydrides having 2-3 hydrogen atoms per alloy formula unit at room temperature and pressure of 1.0 MPa. Pressure composition desorption isotherm measurements were determined over temperature range 296-473 K. In general, the equilibrium pressure increases and the hydrogen capacity decreases with the increasing copper coontent.
