It was shown that the radiation heat transfer coefficient (R) of the ZrC coating is equal to the characteristic of the fuel cladding (aRZrC=RZr1Nb=0.22) and exceeds the characteristic of the CrC coating (aRСrC=0.17). The softening of coal sorbents as a result of CH3I absorption, caused by the manifestation of the Rebinder effect, was established. It is 37.6% for RN11 and C40/4 Extra 1.5 KJ coal, respectively. Comprehensive studies of the electrophysical, thermophysical and dissipative properties of the high-entropy alloy Al0.5CoCuCrNiFe in different structural states: as-cast (I) and after annealing (II) were performed. A thermally activated process of structural relaxation (~130-250 K), caused by dislocation relaxation resonance (Ea~0.09 eV), was revealed. It was shown that below 300 K there is an interval in which the charge and heat transfer coefficients of the Al0.5CoCuCrNiFe HES undergo anomalies caused by the mutual conversion of charge carriers of opposite sign.
