Abstract

The object of the invention is to create high-tensile molded bodies that are made of titanium alloys and are malleable at room temperature and that, compared with the metallic glasses, have macroscopic plasticity and work hardening, without other properties, such as breaking resistance, elastic elongation or corrosion behavior being thus greatly impaired. The molded bodies according to the invention are characterized in that they are made of a material that in its composition conforms to the formula Ti.sub.a E1.sub.b E2.sub.c E3.sub.d E4.sub.e, where E1 comprises one or more elements of the group containing the elements Ta, Nb, Mo, Cr, W, Zr, V, Hf and Y, E2 comprises one or more elements of the group containing the elements Cu, Au, Ag, Pd and Pt, E3 comprises one or more elements of the group containing the elements Ni, Co, Fe, Zn, Mn and E4 comprises one or more elements of the group containing the elements Sn, Al, Ga, Si, P, C, B, Pb and Sb, where a=100-(b+c+d+e), b=0 to 20, c=5 to 30, d=5 to 30, e=1 to 15 (a, b, c, d, e in atomic %). The molded bodies have a homogenous microstructure, mainly comprising a glassy or nanocrystalline matrix with ductile dendritic body-centered cubic phase embedded therein. A third phase with low volumetric proportion can be present. Such molded bodies can be used as high-stress components, e.g., in the aircraft industry, space aviation and the automobile industry, but also for medical technical equipment and implants in the medical field.
