Abstract Binary NiTi alloys are the most common shape memory in medical applications, combining good mechanical properties and high biocompatibility. In alloys, effect is caused by transformation of an austenite phase to a martensite reverse process. Transformation temperatures strongly influenced exact chemical composition presence precipitates microstructure induced thermo-mechanical treatmen...

The shape recovery characteristics of titanium nickelide with an Ni content 50.0 at % and 50.7 were studied in a wide range structures obtained as result cold drawing accumulated true strain e = 0.52 subsequent annealing the 250 to 700 °C temperature range. Shape memory effect (SME) inducing was carried out by bending using non-isothermal loading mode, which made it possible reveal implementing...

Recrystallization and structural recovery in α-decay damage in zircon samples have been studied using Raman spectroscopy. Fifteen zircon samples with different degrees of radiation damage have been thermally annealed between 600 K and 1800 K for up to 28 days and 8 hours. The experimental results from this study reveal that recrystallization in the damaged zircon samples is a multi-stage proces...

Many astrophysical systems can be approximated as isothermal spheres. In an isothermal sphere, the “foreground” objects can act as lenses on “background” objects in the same distribution. We study gravitational lensing by a singular isothermal sphere analytically. Our results may have interesting applications. PACS numbers: 98.62.Sb, 95.30.Sf Typeset using REVTEX 1

The components interaction in the Ho–Ni–In system was investigated by X-ray powder diffraction and, partially, scanning electron microscopy with energy-dispersive spectroscopy. Isothermal section of phase diagram constructed full concentration range at 870 K. samples were synthesized an arc-furnace on a water-cooled Cu-plate under argon atmosphere and annealed silica tubes K for 720 h. analysis...

Herein we show that two isothermal amplification strategies, rolling circle amplification and junction probe strategy, can be used in tandem in the same tube under isothermal conditions to detect HPV16 in clinical cervical swabs. It was discovered that the prior treatment of the clinical sample with a cocktail of restriction endonucleases (REAses) to digest the genomic DNA facilitated the isoth...

non-isothermal crystallization kinetics of polypropylene (pp) and pp containing 0.5 wt% singlewalled carbon nanotubes (pp/swnt) were studied at various cooling rates using differential scanning calorimetry technique. the non-isothermal melt crystallization data were analyzed according to ozawa and cazé-chuah models. although ozawa model was successful in describing the nonisothermal crystalliza...

Isothermal hemodialysis to improve intradialytic tolerance in hypotension-prone patients has been effective in outpatient settings. The purpose of this pilot study was to examine thermal control in an acute care setting and describe comfort issues associated with thermal control. Although complaints of cold or shivering occurred more frequently with the isothermal hemodialysis group, cold disco...

Softening frequently occurs in dual-phase steels under isothermal tempering of martensite. Recently, non-isothermal tempering is implemented to decrease the softening process in dualphase steels. Here, we have discovered using high power electropulsing treatment can significantly enhance the strengthening effects via the formation of ultrafine-grained ferrite with nano-cementite particles in te...
