M.Boulghallat, A. Jouaiti, L.Lallaam, A. Barroug, D. Dafir
Our objective in this study is to try the one hand to increase the equilibrium pressure of ZrCr2 hydride (0.012 bar at 50C) without much changing its large storage capacity for approximately (4H/formula) and improve on the other hand the low storage capacity of ZrFe2 ( 0; 12H/formula).Such modifications can be made by a set of substitution between Cr and Fe in the Zr (Cr1-x Fex) 2 compounds. Hexagonal (C14) Laves phases Zr (Cr1-x Fex) 2 alloys with x = 0.4 ; 0.6 and x = 0.75 have been prepared by arc melting and the corresponding hydrides were formed by hydrogen uptake under pressure. X-ray diffraction have been mesured and analyzed with the Rietveld method.57Fe spectra mesured at room temperature coled by fitted with two doublets 3: 1 area ratio corresponding to the two Fe in the ( C14) structure. The hydrides showed volume expansion without any cristal change.The isotherms P-C-T of these intermetallic compounds were studied by microthermogavimetry at different temperatures under high hydrogen pressure
