Crystal Structure Defects in Titanium Nickelide after Pressing at Lowered Temperature.

The experimental results regarding the effect of warm (573 K) pressing with an increase in the specified true strain, , up to 9.55, on the microstructure and crystal structure defects (dislocations, vacancies) of the TiNi (at %) alloy are presented. It is shown that all samples (regardless of ) have a two-level microstructure.

Structure and Phase State of TiNi (at%) Hydrogenated in Normal Saline.

The paper analyzes the surface structure and phase state of TiNi (at%) hydrogenated at 295 K in normal saline (0.9% NaCl aqueous solution with pH = 5.7) at 20 A/m for 0.

Yield Stress and Reversible Strain in Titanium Nickelide Alloys after Warm Abc Pressing.

The results of the position analysis of the yield stress τ on the "stress-strain" (τ-γ) dependences, received at the torsion of specimens of TiNi (at%) alloy are presented. The critical stress τ (IV), corresponding to the end of linear stage III and the beginning of the intensive development of plastic strain at stage IV, preceding the fracture of the specimens, were obtained as well. The structure of the specimens was transformed from coarse-grained to microcrystalline as a result of warm (723 K) abc pressing with a true deformation of 8.
