Abstract

The master Zr(V_1-xFe_x)₂ (x=0.15) alloy was prepared by the arc-melt method. The alloy was re-melted and melt-spun by single-roller melt spinning at the various copper wheel velocity. From phase analysis and microstructure investigation, it has been shown melt-spun technique could prevent the residual phases of peritectic reaction during solidification and eliminate the dendritic segregation in the as-cast state. The ribbons spun at various velocities could absorb about 2% H/M hydrogen without changing their structure. For the alloy spun at each speed, the cell volume expansion with the saturated hydrogen absorption is about 20% and the he equilibrium pressure is less than 10^-5Pa at room temperature extrapolated by Van't Hoff equation.
