The temperature dependence of the kinetic characteristics (electrical conductivity, thermal conductivity and termoelectromotive force factor) of iron-nickel-titanium alloys (Fe-26.6Ni-2.65Ti-0.02C-0.024Si) and iron-nickel-aluminum alloys (Fe-25.8Ni-2.15Al-0.17Si-0.02C-0.17Mn) in martensite-austenite states in the temperature range of 4.2-1173 K was studied. The Lorenz coefficient was calculated on the basis of the experimental data and changes in the phase-structure transitions in these alloys were analysed.
