Claim:
High strength, beryllium-free, molded zirconium alloy object, which is plastically deformable at room temperature, wherein the molded object comprises a material, a composition of which corresponds to the formula: Zr a (E1) b (E2) c (E3) d (E4) e in which: E1 is an element or several elements selected from the group consisting of Nb, Ta, Mo, Cr, W, Ti, V, Hf, and Y, E2 is an element or several elements selected from the group consisting of Cu, Au, Ag, Pd and Pt, E3 is an element or several elements selected from the group consisting of Ni, Co, Fe, Zn and Mn, and E4 is an element or several elements selected from the group consisting of Al, Ga, Si, P, C, B, Sn, Pb and Sb, wherein a=100−(b+c+d+e) b=5 to 15 c=5 to 15 d=0 to 15 e=5 to 15 (a, b, c, d, e in atom percent); the molded object has a homogenous, microstructural structure, which comprises a glassy or nanocrystalline matrix, in which a ductile, dendritic, cubic, body-centered phase is embedded; and the dendritic, cubic, body-centered phase contained in the material has a composition of Zr f (E1) g (E2) h (E3) i (E4) j with g=7 to 15, h=3 to 9, i=0 to 3 and j=7 to 10, and E1, E2, E3, and E4 as defined above, and f=100−(g+h+i+j).
