Microstructure, grain boundary evolution and anisotropic Fe segregation in (0001) textured Ti thin films
Abstract
The structure and chemistry of grain boundaries (GBs) are crucial in determining polycrystalline materials' properties. Faceting and solute segregation to minimize the GB energy is a commonly observed phenomenon. In this paper, a deposition process to obtain pure tilt GBs in titanium (Ti) thin films is presented. By increasing the power density, a transition from polycrystalline film growth to a maze bicrystalline Ti film on SrTiO3 (001) substrate is triggered. All the GBs in the bicrystalline thin film are characterized to be Sigma 13 [00 01] coincident site lattice (CSL) boundaries. The GB planes are seen to distinctly facet into symmetric {(7) over bar 520} and {13 (4) over bar0} and asymmetric {10 (1) over bar0} // {11 (2) over bar0} segments of 20-50 nm length. Additionally, EDS reveals preferential segregation of iron (Fe) in every symmetric {(7) over bar 520} segment. Both the faceting and the segregation are explained by a difference in the CSL density between the facet planes. Furthermore, in the GB plane containing Fe segregation, atom probe tomography is used to experimentally determine the GB excess solute to be 1.25 atoms/nm(2). In summary, the study reveals for the first time a methodology to obtain bicrystalline Ti thin films with strong faceting and an anisotropy in Fe segregation behaviour within the neighbouring GB facets.
