The analysis of the effect of heat treatment in various atmospheres on the structure of titanium foil

Abstract

The structure and elemental composition of titanium foil annealed in an inert ambient in the presence of hydrocarbons are studied by optical microscopy and scanning electron microscopy. The heat treatments carried out are simulated the synthesis process of multi-walled carbon nanotubes. As a result of the treatments, the plasticity of the material under study is significantly reduced. It is shown that the structure of the foil changes as a result of annealing. With an increase in the annealing temperature, an increase in carbon and oxygen concentrations is observed, and the hardness of the material increases significantly, which is probably due to the formation of titanium oxide and titanium carbide in the foil structure.
