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: Zr(E1)(E2)(E3)(E4), 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&#x2212;(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.

The production of compact molded bodies of rare-earth transition-metal boron carbide and boron nitride compounds configured so as to avoid a selective evaporation of individual components in the production process and enable an exact adjustment of the desired stoichiometry. The process is characterized in that
