  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, and biocompatibility. The non-equilibrium
molecular dynamics simulation was applied to study the influence of porosity
degree on mechanical properties of porous amorphous titanium nickelide at
uniaxial tension, uniaxial compression, and uniform shear. We have found that
the porous amorphous alloy is characterized by a relatively large value of
Young's modulus in comparison to its crystalline analogue. It has been found
that the system with a percolated network of pores exhibits improved elastic
characteristics associated with resistance to tensile and shear. The system
contained isolated spherical pores is more resistant to compression and less
resistant to tensile and shear. These results can be applied to develop and
improve the methods for making amorphous metal foams.
