ABSTRACT:
High-strength, beryllium-free moulded bodies made from zirconium alloys which may be plastically deformed comprise a material essentially corresponding to the following formula in composition: Zra(E1)b(E2)c(E3)d(E4)e, where E1=one or several of Nb, Ta, Mo, Cr, W, Ti, V, Hf and Y, E2=one or several of Cu, Au, Ag, Pd and Pt, E3=one or several of Ni, Co, Fe, Zn and Mn, E4=one or several of AI, Ga, Si, P, C, B, Sn, Pb and Sb, a=100−(b+c+d+e), b=5 to 15, c=5 to 15, d=0 to 15 and e=5 to 15 (a, b, c, d, e in atom %). The moulded body essentially comprises a homogeneous, microstructural structure which is a glass-like or nano-crystalline matrix with a ductile, dendritic, cubic body-centered phase embedded therein.
