Description 493-501
In current work, thermal conductivity, enthalpy of fusion, specific heat, and thermal diffusivity of the Al-8.8La-1.2Ni
cast alloy has been investigated. Chemical element analysis of the studied alloy was determined with X-Ray Fluorescence
Spectrometer (XRF) and SEM microscopy with Energy Dispersive X-Ray Spectroscopy (EDS). Thermal conductivity of ascast
Al-8.8La-1.2Ni alloy was measured using comparison cut bar method in the temperature range of 308–773 K. Thermal
conductivityvalues decreased gradually in the studied alloy with the increase of temperature. The thermal temperature
coefficient was calculated from the thermal conductivity-temperature graph. The heat flow-temperature curve was obtained
by performing Differential Scanning Calorimetry (DSC) analysis. Enthalpy of fusion and specific heat values were also
determined. Thermal diffusivity values were calculated as a function of temperature using the relevant equation. It was
determined that the thermal diffusivity values increased with increasing temperature.
