Definitions

  • the invention relates to high-tensile molded bodies that are made of titanium alloys and are malleable at room temperature.
  • 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, where high demands are made on the mechanical load-bearing capacity, corrosion resistance and surface stressing, in particular with complicated molded components.
  • composition ranges of multi-component alloys are known in which such metallic glasses can also be produced through casting processes in a solid form, e.g., with measurements>1 mm.
  • Such alloys are, e.g., Pd—Cu—Si, Pd 40 Ni 40 P 20 , Zr—Cu—Ni—Al, La—Al—Ni—Cu (see, e.g., T. Masumoto, Mater. Sci. Eng. A179/180 (1994) 8-16 and W. L. Johnson in Mater. Sci. Forum Vol. 225-227, pp. 35-50, Transtec Publications 1996, Switzerland).
  • metallic glasses are known with compositions of the chemical formulas Ti 50 Ni 25 Cu 25 , Ti—Be—Zr, Ti—Ni—Cu—Al and Ti—Zr—Ni—Cu, which can be produced>1 mm (A. Inoue et al., Mater. Lett. 19,131 (1994), K. Amiya et al., Mater. Sci. Eng. A179/A180,692 (1994), L. E. Tanner et al., Scr. Met. 11, 1727 (1977), and D. V. Louzguine et al., J. Mater. Res. 14, 4426 (1999)).
  • a composition for a multi-component beryllium-containing alloy with the chemical formula (Zr 100-a-b Ti a Nb b ) 75 (Be x Cu y Ni z ) 25 is known.
  • This alloy is diphase, it has a high-tensile, brittle, glassy matrix and a ductile, malleable dendritic body-centered cubic phase.
  • the object of the invention is to create high-tensile molded bodies that are malleable at room temperature and made of titanium alloys and that, compared with the referenced metallic glasses, have macroscopic plasticity and work hardening with forming processes at room temperature, without other properties such as strength, 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 a E1 b E2 c E3 d E4 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
  • the molded bodies thereby have a structure with a homogenous microstructure, mainly comprising a glassy or nanocrystalline matrix with ductile dendritic body-centered cubic phase embedded therein.
  • the occurrence of a third phase with low volumetric proportion of a maximum of 10% is possible.
  • the volumetric proportion of the formed dendritic body-centered cubic phase in the matrix is 20 to 90%, preferably 50 to 70%.
  • the length of the primary dendrite axes is in the range of 1-100 ⁇ m and the radius of the primary dendrites is 0.2-2 ⁇ m.
  • the finished cast part is produced by casting the titanium alloy melt in a copper mold.
  • the analysis of the dendritic body-centered cubic phase in the glassy or nanocrystalline matrix and the determination of the size and volumetric proportion of the dendritic deposits can take place via x-ray diffraction, scanning electron microscopy or transmission electron microscopy.
  • An alloy with the composition Ti 50 Cu 23 Ni 20 Sn 7 (figures in atomic %) is cast in a cylindrical copper mold with an internal diameter of 3 mm.
  • the molded body obtained comprises a partially glassy, partially nanocrystalline matrix and ductile body-centered cubic phase embedded therein.
  • the volumetric proportion of the dendritic phase is estimated at 50%.
  • a breaking elongation of 7.5% with a breaking resistance of 2010 Mpa is thus achieved.
  • the elastic elongation at the technical yield point (0.2% yield strength) is 2.5% with a strength of 1190 MPa.
  • the modulus of elasticity is 85.8 GPa.
  • An alloy with the composition Ti 60 Ta 10 Cu 14 Ni 12 Sn 4 (figures in atomic %) is cast in a cylindrical copper mold with an internal diameter of 3 mm.
  • the molded body obtained comprises a partially glassy, partially nanocrystalline matrix and ductile body-centered cubic phase embedded therein.
  • the volumetric proportion of the dendritic phase is estimated at 50%.
  • a breaking elongation of 3.0% with a breaking resistance of 2200 MPa is thus achieved.
  • the elastic elongation at the technical yield point (0.2% yield strength) is 1.0% with a strength of 1900 MPa.
  • the modulus of elasticity is 95.5 GPa.
