Theoretical Properties of Ni₂Ti alloys Studied :by Gaussian 09 Program

Abstract

Abstract The results obtained from theoretical calculations using the Gaussian 09 program using density functional (DFT) theory through calculated each of structural, electronic, thermal, and mechanical properties such as Poisson’s ratio, Young’s modulus, and shear modulus from the elastic constants calculated for Ni 2 Ti. Also, that prepared these alloys and tested on people of both sexes to learn how important it is to improve orthodontic treatments and found that the results obtained in experimental and theoretical compatible to some extent.
