Abstract
The structural and elastic properties of Ti3Al compound were investigated using the generalized gradient approximation (GGA) with ab initio method based on density functional theory (DFT). The independent elastic constants of Ti3Al compound were calculated and the results show that Ti3Al compound is mechanically stable. Some polycrystalline quantities such as the lattice constant, elastic constants, bulk and shear modulus, Young’s modulus, and Poisson’s ratio of Ti3Al compound were derived from calculated elastic constants. The obtained results were compared with the existing experimental and other theoretical data.
