The effect of severe plastic deformation by torsion (SPDT) in Bridgman anvils at a high pressure (6 GPa) on the physical properties
and crystal structure of the shape memory alloy Ti49.5Ni50.5 has been studied. The behavior of the thermal expansion, electrical resistivity, absolute differential thermopower, Hall
coefficient, magnetic properties, and optical characteristics of the amorphous/nanocrystalline and submicrocrystalline alloys
obtained by the SPDT with subsequent heat treatment at 800 K has been discussed. 相似文献

The effect of one-percent substitution of iron for manganese on the physical (magnetic, electrical, thermal, and galvanomagnetic)
properties and the crystal structure of the Ni54Mn21Ga25 alloy has been investigated. It has been demonstrated that the deviation of the alloy composition from the stoichiometric
composition Ni50Mn25Ga25 leads to the formation of a mixed ferromagnetic-antiferromagnetic state. The atomic disordering and nanostructuring of the
alloys under investigation due to the severe plastic deformation by torsion in Bridgman anvils to sizes of 10–20 nm result
in the suppression of reversible magnetically controlled shape memory effects. 相似文献

A series of derivatives of the natural sesquiterpene lactones alantolactone (1) and isoalantolactone (2) was prepared. The α-methylene-γ-lactone moiety was retained in the structures of these for further modifications using reactions
that affected exclusively the nonconjugated double bonds of the decalin ring.
