Phase Composition and the Effect of Thermal Cycling for VH(sub x) V(sub 0.995) C(sub 0.005)H(sub x) and V(sub 0.975)Zr(sub 0.020)C(sub 0.005)H(sub x)
X-ray diffraction (XRD) studies were performed on hydride phases formed by vanadium and its carbon substituted alloys. It was previously found that thermal cycling of VHx across the B-y mixed phase region changed the reversible hydrogen storage capacity and other properties.
