This study addresses the mechanical behavior of lattice materials based on flexible thermoplastic polyurethane (TPU) with honeycomb and gyroid architecture fabricated by 3D printing. Tensile, compression, and three-point bending tests were chosen as mechanical testing methods. The honeycomb architecture was found to provide higher values of rigidity (by 30%), strength (by 25%), plasticity (by 18%), and energy absorption (by 42%) of the flexible TPU lattice compared to the gyroid architecture. The strain recovery is better in the case of gyroid architecture (residual strain of 46% vs. 31%). TPUs with honeycomb architecture are characterized by anisotropy of mechanical properties in tensile and three-point bending tests. The obtained results are explained by the peculiarities of the lattice structure at meso- and macroscopic level and by the role of the pore space.

We have presented the results of an investigation and analysis of the effect of deformation-heat treatment using multidirectional deformation and equal-channel angular and multiple angular pressing on the mechanical properties and critical parameters of low-temperature superconductors based on Nb-Ti alloys. Primary attention has been given to the equal-channel multiple angular pressing which leads to a substantial improvement of their functional characteristics. Physical mechanisms of identifying the effects of structural modifications have been discussed.

The influence of combined deformation, including equal-channel multiangle pressing (ECMAP), and heat treatment on the critical current density of a superconducting wire made from the alloy Nb+60at.% Ti is investigated. It is found that the combined deformation, including ECMAP, can increase the critical current density by up to two times. The relationship between the character of the structural inhomogeneities and the pinning force is estimated. The pinning efficiency is linked to the nanostructural state of the alloy.
