Optical properties and electronic structures of B2 and B19′ phases of equiatomic Ni-Ti alloys
The dielectric functions of equiatomic Ni-Ti alloys were measured by spectroscopic ellipsometry in the energy range of 1.5–5.4 eV at ∼423 and at ∼25 K. The peak at ∼2.26 eV in the B19′ (monoclinic structure) optical conductivity spectrum has a slightly larger magnitude than in the B2 (cubic CsCl structure) phase, while the shoulder at ∼3.5 eVbecomes weaker and almost indiscernible upon martensi...
متن کاملMartensitic transformation and shape memory effect in B2 intermetallic compounds of titanium
2014 Crystallographic and kinetic characteristics of martensitic transformations and parameters of shape memory effect in B2 compounds of titanium Ti50Ni50-xXx (X = Fe, Co, Pd, Pt, Au, Cu) and Ti50Pd50-xYx (Y = Fe, Co, Cu), where 0 ~ x ~ 50 are investigated. Temperature, hysteresis, value of reversible deformation and stress of martensitic shear for martensitic transformations and shape memory ...
متن کاملDamping Characteristics of Ti50Ni50−xCux (x = 0~30 at.%) Shape Memory Alloys at a Low Frequency
The damping characteristics of Ti50Ni50-xCux (x = 0~30 at.%) shape memory alloys (SMAs) at a low frequency have been studied using a dynamic mechanical analyzer. The magnitude of the tan δ value and the values of the storage modulus (E₀) softening/hardening and the strain variation exhibited in B2↔B19 transformation are all higher than those in B2↔B19' transformation. The larger E₀ softening/ha...
متن کاملParvovirus B19.
N Engl J Med 2004;350:586-97. Copyright © 2004 Massachusetts Medical Society. vonne cossart, an australian virologist working in london in the mid-1970s, noted an anomalous reaction of a normal blood donor’s serum (occupying position 19 in plate B) in an assay for hepatitis B. When Cossart excised the line of antigen–antibody precipitation, she saw the particles shown in Figure 1A, and in this ...
متن کاملParvovirus B19 in pregnancy.
Parvovirus B19 is a widespread infection that may affects 1-5% of pregnant women, mainly with normal pregnancy outcome. The prevalence of infection is higher during epidemics - between 3 and 20% with sero-conversion rate of 3-34%. Infection during pregnancy can cause a variety of other signs of fetal damage. The risk of adverse fetal outcome is increased if maternal infection occurs during the ...
