| Abstract Scope |
Deformation in intermetallics is achieved by contrivances, such as using materials that deviate from stoichiometry and have metastable disordered structure, adding dopants such as boron or by phase transformations. And B2 structured intermetallics deform to different extent: polycrystalline NiAl (aluminides) elongates up to 1-2 % before fracture; ternary ZrCoNi elongate up to 18 %, respectively. Whilst binary B2 compounds have been explored a lot, only a few pseudo-binary B2 intermetallics have been investigated. This work focuses on Ti-based pseudo-binary intermetallic such as Ti-Ni-Fe. Microstructural and mechanical characterization have been carried out using SEM, XRD, EBSD, bulk compression, micro-indentation and nano-indentation. It is attributed that the variation in properties is not only due to the composition but also due to a cumulative effect of texture, stoichiometry leading to the presence of point defects, such as antisite, grain size and site preference energy due to effective ternary substitution. |
