Abstract:
In cooling mode, the temperature dependence of the specific heat and changes in the thermodynamic functions of alloys of the $\rm Mg$–$\rm La$ system in the temperature range of $300$–$700$ K were studied. It has been shown that with increasing lanthanum concentration, the specific heat of magnesium, especially with the addition of lanthanum from $5$ to $10\%$, noticeably decreases, and increases with increasing temperature. It has been established that with increasing temperature, the enthalpy and entropy of the alloys increase, and the values of the Gibbs energy decrease. The dependence of these functions on the lanthanum content in magnesium is inverse.
