Effect of bismuth additives on the thermophysical properties and thermodynamic functions of aluminum alloy AlFe5Si10

The temperature dependence of the heat capacity of the aluminum alloy AlFe5Si10 with bismuth was studied in the “cooling” mode. It is shown that with increasing temperature, the heat capacity, enthalpy and entropy of alloys increase, and the value of the Gibbs energy decreases. As the amount of bismuth in the initial alloy increases, the heat capacity, enthalpy and entropy of the AlFe5Si10 alloy decrease, while the value of the Gibbs energy increases.
