Study of the Inelastic Behaviour of Structurally Inhomogeneous Porous Titanium Nickelide Materials

This paper presents a study of the inelastic behaviour of structurally inhomogeneous porous materials made of titanium nickelide with the addition of silver nanoparticles obtained by self-propagating high temperature synthesis. The inelastic behaviour of the porous samples was studied by compressive loading at room temperature until failure. Based on the results of the mechanical tests, an increase in the plastic properties, a decrease in the modulus and the elastic limit of the samples was observed with an increase in the amount of silver in the composition. The change in mechanical properties is related to the complex stress state of the inhomogeneous structure of the porous alloys. In order to explain the results obtained, studies of the structure and phase composition of the alloys obtained were carried out using X-ray diffraction analysis, scanning and transmission electron microscopy.
