Аннотация: Abstract—A calorimetric study is performed of the thermodynamics of hydrogenation and dehydrogenationof intermetallic compound (IMC) Ti0.9Zr0.1Mn1.4V0.5 with Laves phase structure C14. Experiments are conductedin the temperature range of 323 to 373 K and hydrogen pressures up to 50 atm. Functional relationsP = f(C), Habs (Hdes) = f(C) (where P is the equilibrium hydrogen pressure, Habs (Hdes) is the partialmolar enthalpy of absorption (desorption), and C=H/IMC) are obtained using a Tian–Calve-type calorimeterconnected to Sieverts volumetric apparatus. It is established that the enthalpies of absorption and desorptionare not constant and change according to the experimental temperature. It is also determined that Cmax =2.9 at 298 K and a hydrogen pressure of 50 atm.
