Bulk titanium with nanometer grain size


The technology for cryo-mehanical fragmentation of grain structure to obtain bulk titanium with nanometer grain size has been created. The fundamental feature of technology: activation of the mechanical twinning at the low temperatures in such metals as titanium, zirconium and others.

Innovative Aspect and Main Advantages

The most significant changes in properties are observed at decreasing of grain size below 100 nm. At the same time, the existing method for producing nanostructured metals with using of equal-channel angular pressing have in this respect a number of significant limitations.

The advantages of the proposed method of cryo-mehanical fragmentation of grain structure:

  • possibility of obtaining bulk nanocrystalline titanium with an average grain size of 30 nm and a more stable structural state of the different purity of the metal, reducing restrictions on the size of semi-finished product and an increase in product mix.
  • relatively small values imposed cryo-deformation (e ≤ 2) using standard equipment for plastic metal working and the consequent development of industrial production of bulk nanocrystalline titanium and zirconium.
  • less energy.

Areas of Application

  • aerospace industry,
  • defense industry,
  • engineering,
  • biomedical devices.
