In this paper, the microstructure and surface of Ti-50.2 at.% Ni alloy samples in a weakly concentrated solution hydrochloric acid coarse-grained ultrafine-grained states were studied. Corrosion damage to acidic solutions occurs by pitting mechanism; pits are observed on scanning electron microscopy atomic force microscopy. This mechanism is characterized localized dissolution metal, which leads formation small corrosion points sample. some areas state, regions intercrystallite found.
The Ti-18Zr-15Nb shape memory alloys are a new material for medical implants. regularities of phase transformations during heating this alloy in the coarse-grained quenched state and nanostructured after high-pressure torsion have been studied. specimens (Q) HPT were annealed at 300-550 °C 0.5, 3, 12 h. α-phase formation occurs by C-shaped kinetics with pronounced peak near 400-450 Q 350-450 state, stops or slows down higher lower annealing temperatures. as result suppresses β→ω...
The amorphous melt‐spun (MS) Ti 50 Ni 25 Cu alloy is subjected to high‐pressure torsion (HPT) at temperatures of 20‐150 °C. bright‐field (BF) TEM images the change as a result HPT processing, view image depends on temperature processing. processing leads decrease in energy structural relaxation during heating up 400 °C, comparison with initial MS ribbons. crystallization decreases after by 40–20 °C (depends processing). In alloy, and subsequent annealing produces noticeably finer grains than...
Vit105 (Zr52.5Cu17.9Ni14.6Al10Ti5 at. %) bulk metallic glass samples were processed by high-pressure torsion and accumulative torsion. By DSC, XRD SANS methods it was shown that allows for achieving high real strains leads to an increase in the free volume significant transformation of structure. Minor crystallization detected after processing.
The influence of thermal cycling (TC) with a large number cycles on the microstructure, parameters martensitic transformations (MTs), and mechanical properties Ti-50.8 at.% Ni shape-memory alloy in coarse-grained (CG) ultrafine-grained (UFG) states was investigated. effect microstructural stability found both starting from 100th cycle transformations. In addition, an unusual temperature change observed occurring formation intermediate R phase.
The article represents results of influence different severe plastic deformation (SPD) techniques on TiNi alloys. It is demonstrated that strength and shape memory effect (SME) can be significantly enhanced due to formation ultrafine-grained (UFG) nanocrystalline (NC) structures by SPD. Influence equal channel angular pressing (ECAP), high pressure torsion (HPT), multi-step SPD deformations (ECAP plus cold rolling) structure, mechanical functional properties alloys considered. There are...
Abstract Comprehensive studies on the impact of multiple martensitic transformations B2‐B19′ structure and properties ultrafine‐grained nanocrystalline titanium‐nickel alloys are implemented. It is shown that in coarse‐grained, consecutive changes take place, which induced by phase hardening, when number thermocycles increases up to n = 100 with quick heating cooling ‐196 °C. During thermal cycling coarse‐grained Ti 50 Ni via chosen regimes, direction transformation temperatures changes....
