摘要

The structural, elastic and electronic properties of Ti_2SiN were studied by first-principle calculations. The calculated bond lengths of TiSi and TiC are 2.65 and 2.09 ?, respectively. The results show Ti _2SiN is mechanically stable, and its bulk modulus B, shear modulus G, Young's modulus E, Poisson's ratio μ and anisotropy factor A are determined to be 182 GPa, 118 GPa, 291 GPa, 0.233 and 1.57, respectively. The calculated electronic structure indicates that Ti_2SiN is anisotropic and conductive.
