Original abstract
In the last years NiTi alloy became a very important material used in many industrial applications (engineering, medicine etc.) mainly thanks to its shape memory effect. In this work we calculate some of the mechanical characteristics of typical NiTi structures (theoretical strength in tensile and shear loading, bulk modulus, Young's modulus etc.) using ab-initio computations and to compare these results with available experimental data. Computed elastic moduli are in a good agreement with available experimental data. Theoretical shear strength of B2 structure lies closer to the value for pure Ti then to that of Ni.
