ABSTRACT

The results of measurements of heat conduction (К), heat capacity (CP), electrical resistance (r) and data of differentially scanning calorimetry (DSC) of Ni50.2Mn39.8In10 Geissler alloy in Т=25 – 350 К interval are given. The anomalies evidencing on the phase transitions of I and II orders with TC=321 К, MS=296 К are observed on curves of DSC and CP(T). The strong increase of heat conduction at transition martensite – austenite ΔK=3.2 Vt/m*К caused by the increase of electron contribution because of the electron mobility increase at transition in high-symmetry phase, is revealed. The lattice heat conduction changes insignificantly at the transition that shows on the insensibility of phonons to structural disorder.

Keywords: Geissler alloys, heat conduction, heat capacity, phase transitions, electrical resistance.
