Maximum cold rolling reduction rates of as-cast Nb40Ti30xZrxNi30 alloys were measured to evaluate ductility by measuring the change in the thickness. 50 % or higher reduction rates were obtained for the alloys containing the Zr content of 12mol % or less, but lower values were obtained for the alloys substituted with more Zr. Changes of hydrogen permeability () and microstructures of the Nb40Ti18Zr12Ni30 alloy caused by cold-rolling and subsequent vacuum annealing were investigated.  of this alloy was reduced to the half of the as-cast one by the 50% reduction rate, but recovered to 3:23  108 [molH2m1 s1 Pa0:5], which is 1.13 times higher than that of as-cast one, by a subsequent annealing for 360 ks at 1273K. Although the eutectic phase disappeared and was replaced by a small spherical (Nb, Ti, Zr) phase embedded in the (Ti, Zr)Ni matrix after rolling and subsequent annealing, these alloys showed good resistance to the hydrogen embrittlement at 523K or more.
