The porous titanium nickelide is very popular in various industries due to unique combination of physical and mechanical properties such as shape memory effect, high corrosion resistance, biocompatibility. non-equilibrium molecular dynamics simulation was applied study the influence porosity degree on amorphous at uniaxial tension, compression, uniform shear. We have found that alloy characteri...
